My teacher made me watch this
same
Same😹 for physics
@@Prod_REDX for chemistry isn't??!

That’s worse than High Fructose Corn Syrup

This is the best way to procrastinate on TH-cam.
@ S L : He didn't pull it up. It expands and pushes itself up from the bottom. You can look up the experiment anywhere else. It does the same thing. He just kept it going STRAIGHT UP instead of curling to the side.
he has a very sweet smile
I find it amazing that we can make pure carbon out of simple sugar so easily. If I make a very, very thin layer of sugar on a very flat surface, and if I put sulfuric acid on it, any chance I can produce graphene?
Just use tape and pencil lead
@@legoworks-cg5hk Except it would be pure graphene
no this process forms carbon only in a non organized crystal called amorphous carbon, tho you could use amorphous carbon to make pure graphene
If you ever do this, make sure you are in a well ventilated area, outside is best, that beaker is going to get very hot, and make sure not to breath any of the smoke/fumes.
Seriously, I huffed this and now believe the 2020 election was stolen.
It's not pure carbon. It's a pile of carbon and various organic compounds, plus residual acid.
No, you can't produce graphene like that.
Good way to treat constipation.
is he insane in the mind. Always work in the fume-cupboard if you work with highly concentrated acids. cool reaction though, you produced the nicest carbon snake on youtube
I know your comment is 5 years old but you are right, one MUST work under fume hood when using volatile acids like that. However, given the shape of the fumes (1:29) that look sucked in in the lower right corner, i think there is a powerful aspiration or air pressure coming from behind /above the experimentator.
@@arowhite what gas is being produced here? SO2?
who's tearcher sent them here on a online lesson
yessir
This is some Hogwarts level fuckery. Very cool. Thank you for this.
bruh my teacher made me watch this
Hi, I was messing around with a can of deodorant, I sprayed some in a sealable bag that had sugar in, I soon started to realise they reacted and caused the bag to inflate
sugar contains hydrogen, carbon, and oxygen, so you can rip water from sugar.
But with petroleum or gasoline you mostly have chains of carbon surrounded by hydrogen. No oxygen, no way to rip out / split off water. So something else will happen, i still say something will happen because sulfuric acid is so highly corrosive and reactive.
petrolium/gasoline are both highly complex mixtures of a huge variety of compounds, i guess some compounds will react with the acid, but not others.
great
Damn I did not expect it to look like that
best watched while eating
It looks kinda like when cotton candy hits hits liquid and gets all like mushed together and stuff but black.
10 years later and I come upon this video because the "Count Reuven's Treasure" quest in The Witcher 3 brought me here. Cool!
oh hey its off
I want to show this demonstration to my students. Is the gas dangerous or is it just water vapor? How do you dispose of the carbon?
the start of the video haunts my dreams.
Super
Nice
What would happen if you ate it?
any chemical dissolved sugar
@mehedi hassan
I’m not too sure about that, because Liquid Mercury would not dissolve sugar
I don’t think 🤔?
That's about the size shit I took this morning. Not impressed.
is the sulfuric acid highly concentrated ?? tks
Yup
What molarity acid was used? I think I'm going to use this for a demonstration in my AP chemistry class.
It’s been EIGHT LONG YEARS, someone please just answer the damn question!! WHAT IS THE MOLARITY??
Cheap/technical concentrated 95% is fine. It has to be hygroscopical H2SO4 obviously 😉
98.08g/mol btw. I looked it up for you so the original question is answered
what sould happen if sulfuric acid mixes with petroleum or gasoline?
Hi. Great video(s). We've done this before with our kids at home. QUESTION: How can I test that the product is fully neutralized (the acid) and that the sugar is completely spent?
I'd like to use this perhaps as a source of elemental carbon for, say, making ink or tempera paints. But I want to make sure there's no residual acid / sugar ... without contaminating the elemental carbon. I guess maybe rinse it through filters first with sodium bicarbonate and then water?
What this means?
Ha ha! Lonnie got a carb-on!
Would you get the same dramatic results using any acid(e.g. Hydrochloric acid) or is it the specific properties of the sulfuric acid that makes this reaction possible?
I'm not sure, as chlorhydric acid doesn't really dehydrate.
Yup
Its because sulphuric acid is a strong dehydrating agent and in this reaction it takes all the water and leaves behind carbon .
Reaction:
C12H22O11 on reaction with conc H2SO4 gives 12C and 11H2O
Nice representation..... :)
can someone show me the equation mechanism?
Late but here i go anyways!
saccharose (C12H22O11)(12C+11 H2O) will have the water pulled out of it by sulfuric acid, making you left with only carbon, so it tries to expand and goes upward.
Sugar + Sulfuric = cocke colaaaaa!!!
Dude looks like he's going this experiment at gunpoint lol
Ha to make autofire mixture
And this happened to Malaysia national player yesterday Faisal Halim, attacked by criminal with sulfuric acid. He's now was critical in hospital in icu zone.. might this crime was created by mafia football from JDT club, because the tournament of sumbangsih only left 4 days remained on this Friday
What kind of carbon does it produce? Graphite? Coal?
Just pure elemental carbon, i don't think it goes in any real Cristaline shape.
How to make Coke at home
Looks like black licorice cotton candy
I made the mistake of sticking one of my glass stirring rods on the end, and waiving it around like a flag, until the rod broke :)
Wait? Where did the Sulphur go to?
If your byproducts are Carbon from Carbon based sugar and Sulfur based, SULPHUR-ic acid...
sulfur dioxide gas
@@NickyDana nonono, not at all, the sulfuric acid just pulls the water out to forms intermolecular bonds with the water, the fumes are surelly the water and the acid boiling, as the reaction in itself generates LOTS of heat, and that when water bonds with sulfuric acid it makes a shitton of heat. (That's why you don't add water to acid as it will boil instantly and project acid everywhere).
The sulphuric acid simply acts as a very strong dehydrating agent, and removes 11 water molecules from the sugar (C12H22O11), thereby forming intermolecular bonds with water as said by @kill gaet.
Will there be a harmful mass of so2 produced by this if the room is ventilated with open windows?
dehydration of the sugars, so no.
bcuz of 9gag
How to turn white sugar into molasses.
I don't know about that, but adding molasses to white sugar gives you brown sugar.
Is that carbon a good fuel?
I'm not sure, as it would be pure carbon, it's not packed too tight, and most fuels (octane for example) is a mix of carbon and hydrogen, and it's the hydrogen reacting with oxygen during combustion that gives off the most energy.
so the energy from burning this carbon would be equivalent to burning charcoal.
Our teacher called this the steaming turd experiment
WOW
Cold drink
I think you just need propper ventalation.
He pulled it up....-_____-
Waste of materials, but at least it looks funny
1:25
Anybody from MUS?
Snake? More like MRE turd.
Someone here bc the chemistry teacher told him/her to watch this??😫
idk how he can stand the smell. it smells disgusting, even under the fume hood
BBC
Looks like poo
STAND BACK! THERE'S SCIENCE IN THAT SHIT.
Super
