I have to say - as a person who's worked in the film & video business for over 40 years, your lighting was probably the best I've seen on TH-cam. I first clicked on the video because I remember watching early rocket tests and X-15 flights on TV and in Life magazine. The quality of your production was so good, I was glued to the screen. Also, your delivery and was so smooth and information shared so easily followed, I just really enjoyed it. Really great job. Well done!
@@steel_inquisitor6652 y’all realize that to work in a lab you need good lighting. Plus, the voice overs were nice I’ll agree w u but the lighting needs to be like that if you want to work with chemicals.

Pro tip: while using teflon tape, one should wind the tape in the same direction as the object to be sealed is spun during instalation, also it should be wound from where the threads will finally end up to where they first engage (think like fish scales). This will ensure the tape doesn't bunch and leave gaps that can cause leaks.
Ayy yo, check this shit out! The bitch-ass "full-strength" nitric acid tried to burn this guy's finger but it only left a piss stain. It couldn't even make it through a thin-ass vinyl glove. What a pathetic fucking joke! And what's with the constant smoking? Does it think it looks cool doing that shit? Who the fuck does it think it it? John Lennon? Un-fucking-believable!
I started watching your videos two years ago. They have inspired me to study chemistry and seek a degree in chemical engineering. I just finished my first semester of Ochem. I got to do several of the techniques that you display in your videos in my lab (active extractions, recrystallizations, and bromination to name a few). The whole semester I thought of your videos and how cool it was that I was finally getting emulate them. Keep up the great videos, I love them and am inspired by them!
I imagine "solder smell" comes from lead in solder and porcelain glazes containing lead are quite common still unfortunately, so think that's why he suggested it.
If you're going to use fuming nitric acid to burn stuff, might as well go whole hypergolic hog and try dimethyl hydrazine. That's the combination actually in use in rockets. Stand well back.
I think you're talking about chlorine trifluoride? There have been some proposed uses for it, but the problem is ClF3 is so dangerous that it's liable to damage the rocket, either physically from the explosive reaction with the fuel, or chemically if it starts reacting with bits of rocket. So it's a trade-off - you get higher energy density from your fuel/oxidiser mixture, but you impose extra constraints on the rocket design. Nitric acid burns more controllably, and in addition it passivates many metals which protects the fuel chamber from chemical attack. It's normally a better option unless you really need the highest energy density possible.
I got my information from a very interesting book by a rocket fuel industry insider: library.sciencemadness.org/library/books/ignition.pdf by a guy named John D. Clark. In it he describes the experimental road taken to find the standard liquid fuel combination IRFNA/UDMH, the U standing for unsymmetrical. On the german C-stoff/ T-stoff he writes: "... peroxide is not only a monopropellant, it's also a pretty good oxidizer. And Walter worked out a fuel for it that he called "C-Stoff." (The peroxide itself was called "T-Stoff.") Hydrazine hydrate, N2H4-H2O ignited spontaneously when it came in contact with peroxide (Walter was probably the first propellant man to discover such a phenomenon) and C-Stoff consisted of 30 percent hydrazine hydrate, 57 of methanol, and 13 of water, plus thirty milligrams per liter of copper as potassium cuprocyanide, to act as an ignition and combustion catalyst. The reason for the methanol and the water was the fact that hydrazine hydrate was hard to come by - so hard, in fact, that by the end of the war its percentage in C-Stoff was down to fifteen. The Messerschmitt 163-B interceptor used C-Stoff and T-Stoff. " Check out the PDF if you're into chemistry and things that go boom, very interesting. As for ClF3, he also writes about that, but another great source for that is the series "Things I won't work with" by Derek Lowe, specific entry: blogs.sciencemag.org/pipeline/archives/2008/02/26/sand_wont_save_you_this_time (note the title of the article) The whole series is a delight of horrors :)
Prehistoricman Nile's too smart to be a smoker. People that are successful in academia usually don't smoke because they understand how harmful it truly is.
6:35 Me: "Oh, I bet it's passivating it." ...a few seconds later..."Awwwww, yeah, go me." Passivation is a really interesting thing. You could do a whole video on how different materials actually stop corroding in the presence of stronger and/or more concentrated acids, oxidizers, etc. even though that seems counterintuitive. And I don't see any videos on TH-cam that actually explore passivation chemistry in detail. Here's an example you might consider using from us chemical engineers that's rather important in industry. A very common process from removing H2S and/or CO2 from gas streams is absorption with an amine such as MEA, DEA, or MDEA mixed with water. Amine plants are full of places with corrosion potential. You would probably expect H2S to be the bigger corrosion threat in the absorption column, but that's not actually true. It's usually CO2. Both of them react with the iron in the column which corrodes the steel. However, the iron sulfide layer formed from the H2S forms much quicker and adheres much more strongly than the FeCO3 layer from CO2. And once a solid FeS layer is formed, it actually protects the steel from further corrosion. So for H2S, we actually DESIGN the column to corrode and form that passivating FeS layer to PROTECT against further corrosion. With CO2, you have to take a completely different approach, because FeCO3 just continuously sloughs off, and you can lose a column much faster in the presence of CO2 because of that. Google "h2s passivation amine column" to read more.
We boiled a 1 inch steel cube in Nitric acid for 72 hours for a required corrosion test. It passed, ferric oxide passivates the surface. Thats why our Nitric Acid drums were made of steel.
This is close to the reason aluminum doesn't rust: it does, except that the aluminum oxide just sticks to the metal, forming a protective layer. It's really cool.
DUDE. I have been down a rabbit whole on surface energy, surface activation, and PASSIVATION for the past 4 months and you're right there is SOOOOO little content to go with, especially on passivation. If you find some good videos to watch, please let me know. I know citric acid and nitric acid can be used to passivate SS, but it seems like other acids like muriatic can be used to re-activate it? Not clear if that accurate, but I'm surprised it's not an acid-base thing and would like to learn more. Phosphoric acid seems to be king for corrosion protection on most ferritic metals, but doesn't necessarily put them in a passive state. And since most coatings and finish prefer to bond to an active surface would I want to passivate the phosphated surface or should I keep it active before priming? I HAVE SO MANY QUESTIONS and this is after months of reading and watching.
Forgot to wear gloves during experiment in school and spilled some on my elbow and palm of my hand. Palm of my hand was just fine after rinsing with water but near my elbow it ate trough my skin and left a scar. Your hypotesos was right. On other bodyparts, the pain and damage is almost instant
Got some on my leg once. Couple drops onto bare skin below my knee (wearing shorts when handling chemicals is not recommended) and the stinging started within a half second. I was surprised at how fast it was.
It certainly gave me a new respect for it. I would rank it up there with a bee sting but, as you said, it didn't really linger once it was washed away. Concentrated sulfuric acid left scars on my hand and it hurt but not as much right away. It was the constant throb like you get with thermal burns.
THEDRAFTEDCOW oh thats cool, if you wanna be chemist you should totally try this at some point, before gettin in collage, you know, I meant the guy who was trying to show this to his teacher, probably will get nile im some trouble if he is flagged
Gummy Bugz I build computers all the time, so I'll try to help you out. Could it be that you have an old computer? Maybe one with a very old graphics card, or no graphics card at all? Because of so, then a cheap second hand graphic card ($20 max) could be all you need to solve the problem.
@@JGnLAU8OAWF6 Newer macbooks don't have hte issue, the older ones doo, like the 2012 ones. windows machines have a longer lifespan, and i was able to run 4K60 on my Core 2 Duo/GT 710 system with out an issue other than the RAM speed on the mobo.
I'm an electrical guy. I absolutely HATED my chem classes, even the labs. But these vids actually do a pretty good job at making the process rather interesting, pretty easy to understand, and the chem actually seems like it meets an end goal! My chem classes always made it feel like I have to understand every elements valence shell structure before I'm able to do an experiment that seemed like it was more than just pouring random liquids back and fourth between containers for no understandable greater goal. Totally do the model rocket thing. It would be pretty cool. Even better if maybe it was a collab with someone else to add controls or sensors or a camera or something to the rocket. A regular youtube space center.
I have never before bought youtuber merch, but I copped that t-shirt literally as soon as you started the plug for it. Your videos are the pinnacle of TH-cam chemistry videos. Love the new lab, keep it up!
After reading enough SDSs I have a hard time thinking the people writing them have ever used them. Or better way of looking at it. Read the SDS for unleaded gasoline and then think about how dangerous regular chemical handling is.
I worked in a few PCP shops and the gloves and other safety equipment was not as "dainty" as shown here. Used handheld pumps to fill 150 gallon sulfuric and 2 300 gallon nitric acid tanks. My coworkers were all bald from radiation and Lead exposure. Then I left.
The vinal glove test reminded me of a conversation I had with a friend who owned an E-Waste company. He mentioned some apparatus he made with PVC buckets and tubing because PVC was immune to nitric acid. So big thick PVC gloves might be a good option for safety in this regard.
This is why chemical compatibility charts were created. Also, it's generally advisable to wear thicker over gloves when handling concentrated strong acids 😀
You should get a thermal camera to show how things heat up in a reaction, might have been interesting to see how the temperature in the gloves rose before igniting.
Very intresting process! All your videos are great for learning! I wish I would also have access to such chemicals. There would be a lot more projects possible. Sadly, chemicals are strongly controlled in Austria, so I have to wait until I am done with my chemistry studies and my licence.
Nice, I might give this a try, might be fun to try oxidizing a few materials with this stuff. Also, I think this can be used in conjunction with oleum to produce TNT and other highly nitrated aromatics. Very harsh conditions are required to add so many NO2 groups on those rings.
I had a labmate in college who terrified herself with a nitric acid exposure. She was wearing nitrile gloves, not knowing that nitric can penetrate. If memory serves, it was about 1.5 M so it didn't hurt her. But it did etch away some of the silver in a ring she was wearing and stained her skin with the resulting silver nitrate. She noticed a few hours after lab and I was the third or fourth person she asked but the only one who could tell her what had happened.
We had a large chart for PPE material and chemical resistance up on the wall. Sometimes I would just read it to kill time... however, no where did it say, "Don't wear these as XXX will make it combust before you have time to doff them."
I've watched this video before, but, I want to point out how beautiful that thumbnail is. That is a gorgeous stillframe. It's really hard not to click on it when TH-cam suggests I rewatch it.
0:20 To make make explosives with nitric acid (benzene based) you need to mixed it with concentrate nitric acid and concentrate sulfuric acid. It’s for the “electrophilic aromatic substitution” (EAS): The sulfuric acid reacts whit the nitric acid to form a NO2+ kation and a HSO4- anion. A Benzene electron rich ‘pi-bound’ will react as an nucleophile and add NO2 to his hexane form and form a cyclohexadienyl kation. HSO4- anion must react as an Brönstedt base and needs to eliminate a proton of the cyclohexadienyl kation to recover the aromatic form. I hope I don’t get in trouble whit this reaction 🙄
My STEM class briefly dabbled in rockets but as a high school class we only looked at solid fuels. I would love seeing a liquid-fueled home made rocket engine. I’m bored by my high school chemistry class because what few labs we do put safety at the highest priority. The most dangerous chemical we’ve handled all year is a .1M sodium hydroxide solution. Your videos and reactions are incredible and I love seeing all the cool stuff you’re able to do.
I got nitric acid burns a few years ago from making concentrated nitric acid. The friend i was making it with got permanent scars from trying to impress me and keep it on his hand. So glad i washed it off really quickly with a basic solution
Fuming, check Piss-yellow, check Sets things on fire, check Dangerous af, check Roundbottom flask, Check That's probably the best example for the cartoon chemicals
I have two suggestions for future videos. Since spring is here, I would like to see you extract latex from dandelions. Another suggestion is the extraction of Coniine from Poison Hemlock. Since Nurdrage hasn't been posting every frequently anymore, I think you will be a great substitute.
I was using fuming nitric acid to dissolve a zinc coating in the lab the other day and was wondering if/how gloves would protect me at all. Good thing I didn't get any acid on me!
You can't precisely measure concentration of nitric acid because of no2 contamination,try bubbling dry air into it to remove excess no2 (takes a while) and measure concentration again
Guys, there are volumetric flasks. They're the best for this kind of work. A properly used volumetric flask along with an analytical scale and temperature control can give you a density with 3 accurate decimal numbers.
I like the doing chemistry on yourself thing. “Acid bonded with the keratin in my skin” LIKE WHAT dude thats rad to just know somthing like that. Best youtuber
Hey NileRed, I have been watching your videos almost every night lately during my wind down time. Great stuff. You should consider brewing a beer for your edible chem series. I have been thinking about dabbling in homebrewing for a while and your videos are inspiring me to finally do it. Thanks for your consideration, take care!
That's a great all around video on making fuming nitric acid but what mostly amateurs seemed to forget is keeping the sulfuric acid in excess guarantees more and stronger in concentration nitric acid!
Love your videos. You should make a video concerning some of the pathways of a chemist bachelor’s, and yours maybe. I wonder if you are making these videos as a result of not being able to find chemistry work? Very interested, and it would help me decide if I want to remain as a chemistry major.
Hey, love your videos. I know nothing about chemistry but have always wondered about natural liquids and the difference between them. It might be interesting to do a video about all the natural liquids: water, oil/fat, acids, mercury/other liquid elements, alcohols. Just a thought!!
Dr. Tim Root, an Ophthalmologist has a video where he demonstrates the effects of strong acid on the eye, and he also found that damage does not usually extend to the deeper layers. The eschar (dry charred area of skin formed after a burn) isn't easily attacked by acids, and their reaction will usually stop once it's formed, much like the passivation you encountered with the copper. He also repeated the experiment with a strong base and found that it attacked the eschar as its formed and will react until it's expended itself or makes it through the other end of the pig eye he was testing it on. Fascinating video if you're not squeamish.
That t-shirt logo is pretty damn cool. I like it. Love it when you put acid on your hands. That should be your next t-shirt logo. A hand with fuming nitric acid on it." "Acid is dangerous on skin unless you are Nile Red" What does nitric acid do to real Nile Red anyway?
As someone who has done this...a few extra hints. Do use a vacuum, aspirator preferred. I use a recirculating system with a pump and a bucket of water with NaOH dissolved in it to eat any fumes etc. The reason is that the exotherm of the KNO3/H2SO4 reaction can go out of control and boil over into the rest of the rig. Stop the vacuum, wait a bit, you're good - safety, and not having to throw good glass (or quartz)ware out the window to save your lab. Liter type volumes do this and you should be ready for that. Nitric oxide is no joke...it will nitrate lung tissue and you'll be choking for weeks unless you're young like NileR. Not even 1 diluted cc is acceptable in your lungs. Just don't allow that to happen. I've nitrated a fingertip myself. FWIW, the result can be a super-flammable fingernail, and finding that out is the not-fun part. I love this stuff, I don't want to put anyone off - but do be safe out there.
Very good video! I understood everything! I have two questions for you. Can I use hydrochloric acid (10%) or acetic acid (80%) instead of sulfuric acid? And if you make nitric acid by this way you get K2SO4 or KHSO4?
I'm not always familiar with the English names on your nametags.Would it be possible if you can add the chemical formulas of your ingredients on all tags?
That is definitely true, but I don't want to pause the video every 10 seconds to do some 'research'. It's not needed, but just convenienced if they were on the tags.
And keep the whole video wondering what ingredients he is using? I know you're right, but it was just a suggestio (as I can't be the only one whose native language isn't English)
Bravo! I bought 500ml of fuming nitric acid from a chemistry store in China 20 years ago, and tested putting one drop on the back of my hand. After 2 secs, the pain was intolerable and I had to wash it off. As reference, I can withstand the same test with H2SO4 for 50 secs(the acid burns through skin around 45 secs), regular HNO3 for 20 secs. Maybe it's bc, like you explained, the skin on the back of the hand is much thinner. When I saw you doing the skin test I thought you must have super-human capability LOL
Exposing a glove to the vapors, I.E. using the glove to cover a beaker of the acid for a few hours, will cause it to detonate when struck. Had to learn that one the hard way...

Step aside coke and mentos youtubers, let's see what happends when I ingest nitric acid and monomethylhydrazine.
He did make rockets but that oroject has been dormant for a long while.
He has toyed with (fairly crude) red fuming nitric acid + diesel rockets... th-cam.com/video/iIc142Q7HH8/w-d-xo.html

Hey! I love you! Im gonna be a chem major because of you! 16 in highschool, i love your work. Im trying to make my chem teacher watch this
MrPies32 haha same, I'm 15 an plan on doing the same thing, although I kind of want to go work on the fusion reactors. But teaching does sound fun :)
Plz don’t if they are lame they probably flag this video, the YT chem community is losing good channels bc of unjustified fear
Wait? I think you misinterpreted my statement I want to become a chemist as well, not do this experiment.
THEDRAFTEDCOW oh thats cool, if you wanna be chemist you should totally try this at some point, before gettin in collage, you know, I meant the guy who was trying to show this to his teacher, probably will get nile im some trouble if he is flagged
Sebasfort this is true, but physics is cool as well :)
I know I'm late to the party, but as a casual observer I really appreciate the safety displayed and explained. It's professional and approachable. 😄
Not more late than me

Every now and then I get really sick of studying, then I watch your videos and get reminded of how awesome chemistry really is.
1080p60 is nice... great video
thank!
Would be even better if you'd upscale it to 4k. Give it a try.

I build computers all the time, so I'll try to help you out.
Could it be that you have an old computer? Maybe one with a very old graphics card, or no graphics card at all? Because of so, then a cheap second hand graphic card ($20 max) could be all you need to solve the problem.
I thought Macbook shouldn't have issues with 60fps...
@@JGnLAU8OAWF6 Newer macbooks don't have hte issue, the older ones doo, like the 2012 ones. windows machines have a longer lifespan, and i was able to run 4K60 on my Core 2 Duo/GT 710 system with out an issue other than the RAM speed on the mobo.
7:12 OK I jumped. Chemistry is one of those few university subjects where your homework can eat your dog.
I'm an electrical guy. I absolutely HATED my chem classes, even the labs. But these vids actually do a pretty good job at making the process rather interesting, pretty easy to understand, and the chem actually seems like it meets an end goal! My chem classes always made it feel like I have to understand every elements valence shell structure before I'm able to do an experiment that seemed like it was more than just pouring random liquids back and fourth between containers for no understandable greater goal.
Totally do the model rocket thing. It would be pretty cool. Even better if maybe it was a collab with someone else to add controls or sensors or a camera or something to the rocket. A regular youtube space center.
6:40 I love how the green gets more & more intense! Wow the adding of water gave a really intense reaction!
I have never before bought youtuber merch, but I copped that t-shirt literally as soon as you started the plug for it. Your videos are the pinnacle of TH-cam chemistry videos. Love the new lab, keep it up!
Beautiful just beautiful. Why is it that dangerous things are always so beautiful and mesmerizing.
Keep up the good work man
Unfortunately the SDS for fuming nitric on Aldrich recommends using gloves. That should be changed...
After reading enough SDSs I have a hard time thinking the people writing them have ever used them.
Or better way of looking at it. Read the SDS for unleaded gasoline and then think about how dangerous regular chemical handling is.
I worked in a few PCP shops and the gloves and other safety equipment was not as "dainty" as shown here. Used handheld pumps to fill 150 gallon sulfuric and 2 300 gallon nitric acid tanks. My coworkers were all bald from radiation and Lead exposure. Then I left.
Pvc glives maybe?
mmm those lovely orange gases 😍
Garrett Norris UGHH pneumonia lol
You wouldn't want to breathe it in.
Darth Sagit of course not, I just like the color and think it's a fun compound.
I would.
Monokuma my dude, you okay there?
The vinal glove test reminded me of a conversation I had with a friend who owned an E-Waste company. He mentioned some apparatus he made with PVC buckets and tubing because PVC was immune to nitric acid. So big thick PVC gloves might be a good option for safety in this regard.
If you're gonna do some rocketry you should totally collab with CodysLab
7:50 “hey guys let’s see if this fire is hot, wow it burned my hand how unexpected”
Vinyl gloves are probably just pvc; which is notoriously difficult to ignite.
Your videos have always been very high quality, but you have outdone yourself again! Great Video!
This is why chemical compatibility charts were created. Also, it's generally advisable to wear thicker over gloves when handling concentrated strong acids 😀
You should get a thermal camera to show how things heat up in a reaction, might have been interesting to see how the temperature in the gloves rose before igniting.
Get new glassware? You could probably release a vid unboxing them since new glassware is so super clean. Kinda like a visual ASMR
Double displacement reactions are awesome! I recently learned about them and must say they are quite resourceful in chemistry.
"Hey, nile, how'd you get that yellow stuff on your finger?"
"Fuming nitric acid."
"what"
"F U M I N G N I T R I C A C I D"
That's it. I'm heading right to Patreon to support you right now.
Keep in mind that polyvinyl chloride (vinyl) doesn't burn well PRESUMABLY because of its chlorine content.
man i love how smooth your videos are. it actually feels like 60fps or even more
Very intresting process! All your videos are great for learning!
I wish I would also have access to such chemicals. There would be a lot more projects possible.
Sadly, chemicals are strongly controlled in Austria, so I have to wait until I am done with my chemistry studies and my licence.
You don't have a similar drain cleaner there?
You could just make the chemicals from scratch tho
In Indonesia, you can basically buy sulphuric acid, hydrochloric, nitric acid, or even hydrofluoric acid without any license!
dannes22 yeah like me, I made myself some anfo rocket
@delta seems like asian countries have freer chemical regulations!
Really great production quality on this one!
Nice, I might give this a try, might be fun to try oxidizing a few materials with this stuff. Also, I think this can be used in conjunction with oleum to produce TNT and other highly nitrated aromatics. Very harsh conditions are required to add so many NO2 groups on those rings.
Just forget TNT: 3 deactivating groups in one ring? You deserve a Nobel for Peace if you're patient enough!
Haha, a NOBEL for peace
@@guitrz000 Alfred Nobel made the fortune behind those prizes from his business making explosives.
I had a labmate in college who terrified herself with a nitric acid exposure. She was wearing nitrile gloves, not knowing that nitric can penetrate. If memory serves, it was about 1.5 M so it didn't hurt her. But it did etch away some of the silver in a ring she was wearing and stained her skin with the resulting silver nitrate. She noticed a few hours after lab and I was the third or fourth person she asked but the only one who could tell her what had happened.
We had a large chart for PPE material and chemical resistance up on the wall. Sometimes I would just read it to kill time... however, no where did it say, "Don't wear these as XXX will make it combust before you have time to doff them."
Thank you for explaining why sulfuric acid is used on glass joints
Please make the model rocket!
YEEESSSSSS! PLZ
There is a cool video about this on periodic videos. I think it's about hypergolic reaktions.
I've watched this video before, but, I want to point out how beautiful that thumbnail is. That is a gorgeous stillframe. It's really hard not to click on it when TH-cam suggests I rewatch it.
Who’s here from the truck spill?
Here
Your production quality in the new lab is top notch.
0:20
To make make explosives with nitric acid (benzene based) you need to mixed it with concentrate nitric acid and concentrate sulfuric acid.
It’s for the “electrophilic aromatic substitution” (EAS):
The sulfuric acid reacts whit the nitric acid to form a NO2+ kation and a HSO4- anion. A Benzene electron rich ‘pi-bound’ will react as an nucleophile and add NO2 to his hexane form and form a cyclohexadienyl kation.
HSO4- anion must react as an Brönstedt base and needs to eliminate a proton of the cyclohexadienyl kation to recover the aromatic form.
I hope I don’t get in trouble whit this reaction 🙄
i used to hate chemistry but now it’s my favorite subject at school because of you!
I love how Cody posts making a fume box and you post this lol
Amazing narrator voice Nile!
Started watching your videos at around 8pm and still not enough xD
Another great and interesting vid as always seen from Nile red!
My STEM class briefly dabbled in rockets but as a high school class we only looked at solid fuels. I would love seeing a liquid-fueled home made rocket engine. I’m bored by my high school chemistry class because what few labs we do put safety at the highest priority. The most dangerous chemical we’ve handled all year is a .1M sodium hydroxide solution. Your videos and reactions are incredible and I love seeing all the cool stuff you’re able to do.
3:38 forbidden applesauce
ive rewatched a good number of your videos, a few of them probably 5+ times. never gets old !
7:10 Cleanest air in arizona be like 😤😤
You've stepped up your camera game, well done sir.
We used this in our first semester and it was a bit scary doing it without gloves :)
The reflection of the new lab looks great in the round bottom flask. :)
You want crazy rocket tests? Cody's Lab is just the collab for you!
I got nitric acid burns a few years ago from making concentrated nitric acid. The friend i was making it with got permanent scars from trying to impress me and keep it on his hand. So glad i washed it off really quickly with a basic solution
Fuming, check
Piss-yellow, check
Sets things on fire, check
Dangerous af, check
Roundbottom flask, Check
That's probably the best example for the cartoon chemicals
As a stainless pickling line worker I breathe those fumes daily. Our concentrated acid is 95%. Chronic coughing is a major symptom of breathing it.
0:19 high explosives you say? Demonitized.
I have two suggestions for future videos. Since spring is here, I would like to see you extract latex from dandelions. Another suggestion is the extraction of Coniine from Poison Hemlock. Since Nurdrage hasn't been posting every frequently anymore, I think you will be a great substitute.
I was using fuming nitric acid to dissolve a zinc coating in the lab the other day and was wondering if/how gloves would protect me at all. Good thing I didn't get any acid on me!
You can't precisely measure concentration of nitric acid because of no2 contamination,try bubbling dry air into it to remove excess no2 (takes a while) and measure concentration again
He's also measuring with a graduated cylinder, which isn't exactly accurate.
ethan It's the best accuracy you're going to get anyway.
Guys, there are volumetric flasks. They're the best for this kind of work. A properly used volumetric flask along with an analytical scale and temperature control can give you a density with 3 accurate decimal numbers.
I like the doing chemistry on yourself thing.
“Acid bonded with the keratin in my skin”
LIKE WHAT dude thats rad to just know somthing like that. Best youtuber
Hey NileRed,
I have been watching your videos almost every night lately during my wind down time. Great stuff.
You should consider brewing a beer for your edible chem series. I have been thinking about dabbling in homebrewing for a while and your videos are inspiring me to finally do it.
Thanks for your consideration, take care!
That's a great all around video on making fuming nitric acid but what mostly amateurs seemed to forget is keeping the sulfuric acid in excess guarantees more and stronger in concentration nitric acid!
Love your videos. You should make a video concerning some of the pathways of a chemist bachelor’s, and yours maybe. I wonder if you are making these videos as a result of not being able to find chemistry work? Very interested, and it would help me decide if I want to remain as a chemistry major.
So much information making it's way in my head from this video.
Hey, love your videos. I know nothing about chemistry but have always wondered about natural liquids and the difference between them. It might be interesting to do a video about all the natural liquids: water, oil/fat, acids, mercury/other liquid elements, alcohols. Just a thought!!
Dr. Tim Root, an Ophthalmologist has a video where he demonstrates the effects of strong acid on the eye, and he also found that damage does not usually extend to the deeper layers. The eschar (dry charred area of skin formed after a burn) isn't easily attacked by acids, and their reaction will usually stop once it's formed, much like the passivation you encountered with the copper. He also repeated the experiment with a strong base and found that it attacked the eschar as its formed and will react until it's expended itself or makes it through the other end of the pig eye he was testing it on.
Fascinating video if you're not squeamish.
"The nitrile reacts quicker but may be easier to remove" took you longer to say than the time it took to start burning xD
If I remember right, RFNA was most often paired with Aniline dye as the fuel in rockets.
That t-shirt logo is pretty damn cool. I like it. Love it when you put acid on your hands. That should be your next t-shirt logo. A hand with fuming nitric acid on it." "Acid is dangerous on skin unless you are Nile Red" What does nitric acid do to real Nile Red anyway?
Love your videos man. Keep up the good work
"It worked out better because you could see the heating flask"
*Covers with foil*
I could sit and watch your videos all day long. Huge fan!
That thumbnail looks like Hollow Knights infectious gas.
As someone who has done this...a few extra hints. Do use a vacuum, aspirator preferred. I use a recirculating system with a pump and a bucket of water with NaOH dissolved in it to eat any fumes etc. The reason is that the exotherm of the KNO3/H2SO4 reaction can go out of control and boil over into the rest of the rig. Stop the vacuum, wait a bit, you're good - safety, and not having to throw good glass (or quartz)ware out the window to save your lab.
Liter type volumes do this and you should be ready for that.
Nitric oxide is no joke...it will nitrate lung tissue and you'll be choking for weeks unless you're young like NileR. Not even 1 diluted cc is acceptable in your lungs. Just don't allow that to happen.
I've nitrated a fingertip myself. FWIW, the result can be a super-flammable fingernail, and finding that out is the not-fun part. I love this stuff, I don't want to put anyone off - but do be safe out there.
Well, I learned something new: Nitric acid is something you handle Very Carefully.
Oh yea nitric acid is dangerous as dicks. Highly corrosive? Decomposes into super toxic NO2 gas? Yea that's pretty bad.
You help me fall asleep I’ve watched hours of you and I learn something new every time
At first I read "Making fun of nitric acid" 🤣
You probably wont see this but when ever im having a bad day or i need to sleep i watch you thank you for that
Very good video! I understood everything! I have two questions for you. Can I use hydrochloric acid (10%) or acetic acid (80%) instead of sulfuric acid?
And if you make nitric acid by this way you get K2SO4 or KHSO4?
No, these acids won't work.
"I wont be building an actual rocket." Hes definitely building an ICBM in his workshop
I'm not always familiar with the English names on your nametags.Would it be possible if you can add the chemical formulas of your ingredients on all tags?
Leendert van Egmond You can google them.
That is definitely true, but I don't want to pause the video every 10 seconds to do some 'research'. It's not needed, but just convenienced if they were on the tags.
Leendert van Egmond You can do that after the video.
And keep the whole video wondering what ingredients he is using?
I know you're right, but it was just a suggestio (as I can't be the only one whose native language isn't English)
Leendert van Egmond English isn't my native language either.
Bravo! I bought 500ml of fuming nitric acid from a chemistry store in China 20 years ago, and tested putting one drop on the back of my hand. After 2 secs, the pain was intolerable and I had to wash it off. As reference, I can withstand the same test with H2SO4 for 50 secs(the acid burns through skin around 45 secs), regular HNO3 for 20 secs. Maybe it's bc, like you explained, the skin on the back of the hand is much thinner. When I saw you doing the skin test I thought you must have super-human capability LOL
Just finished my AP Chemistry Exam and you upload a video :/
Henry Jiang why the sad face
longevities The Face I’d get after getting the results.
