1:39 Did he say "You're done having kids arent you? "
He did
I love how he asked her if she is done having kids, after she inhaled fumes that would mutate her future children!
The first he added sulfuric acid to the sugar which turns it to carbon by quickly dehydrating it, the Sucrose which is C12H22O11 breaks down into 12C(Carbon) and 11H2O(Water). Its a very exothermic reaction and produced enough heat to turn the water in the sugar to steam. The second beaker contained Potassium Chlorate (KClO3) which is a strong oxidizer and sugar. Adding acid produces heat by reacting with the sugar, that decomposes some KClO3, and this starts the rapid oxidation of the sugar (o:
Yea...just breathe those fumes in, lol.
"it stinks" yeah those fumes are toxic
"you're done having kids, right?"
He talks so fast and smooth he can say anything to you and you'll just agree without knowing about it.
"The fumes are pretty... yeah"
How come nobody demonstrates sulfuric acid as an acid? I always see it demonstrated as a dehydrating agent.
18 molar means theres 18 moles of acid per liter. so thats 1.7 kg of acid per liter, thats pretty strong for anyone who was wondering (:
days 35, i'm running out of water and food, but i still can't stop watching this science video.
when are we going to come out with the acid squirt guns for the military lol
Sulfuric acid is a strong acid, Steve...
Sulfuric acid is the most reactive acid with organic compounds, wich means it is the most dangerous for your skin (in equal concentrations). Normally it would just burn your skin. Google sulfuric acid chemical burns and you'll see. Hope it helped :)
Awesome! Makes me miss high school chemistry.
it doesnt matter if it has "water" in it, the sulfuric acid just takes H2O from sugar (glucose, c6h12o6) and makes it pure Carbon (the black stuff). The Sulfuric acid (H2SO4) dumps the 2 protons (H+) on the H2O molecules, so they become known as H3O+. Thats what making it hot, it litterly dries the sugar to pure carbon. :)
But very dangerous to do it like this, its getting very hot, with gas formed H2SO4 if you dont watch out....
fluoroantimonic acid protonates virtually all known organic compounds. Since protonation is itself a definition as to the acidity and "strength" of an acid, it is the strongest acid. It doesn't dissociate in water, IT BLOWS IT UP ON CONTACT, it's that badass. Seen as this stuff eats through glass I doubt you want to prove its not corrosive by sticking your hand in.
THAT LOOKS SO AWSOME I SEE PEOPLE DO THAT AT THEIR ROOM
infinite fun with sulfuric acid
I just laughed out loud at this. haha
ISN'T THAT JUST AMAZING!!!!
😂
2:45 yes, because everybody wants pooping sugar at their wedding.
Chemists consider it a weak acid, what does he mean??! It can be reacted with nitrates, phosphates and chlorides to produce nitric acid, phosphoric acid, and hyrogen chloride. It has a pKa value of -3! how much stronger can you get!
Perchoric acid, fluoroantimonic acid
I'd love to see a video on Fluoroantimonic acid. I doubt anyone would be able to get their hands on it though..
I wanna try this at school O-O
Sulfuric acid is a relatively weak acid. Especially when compared to hydoflouric acid for example. Also, it is in fact dangerous when mixed with water. Mixing water with sulfur acid is an exothermic reaction, meaning that it releases heat when mixed.
ahhh just watching this made my nose burn i hate acid fumes
smosh will love this
HOLY SHI- you get the idea..
1:30 WE DID THIS IN CHEMISTRY IN THE BEGINNING OF THE YEAR! :D
wooo denver!
you rock steve
This is the final one im watching....I swear!!!
The question is actually valid. If the question makes sense to someone that isn't an expert then it's considered valid. The answer to said question however is "no".
"This particudar material here, ....so this for example here is sugar, regudar table sugar."
ur done having kids...ouch lol real smooth
a sulfiric asid spill ! he said it at the bigining of the ep (a sulfiric asid spill is a day where it rains sulfuric acid)
well physicists consider gravity to be so weak as to not include it in their formulas but it is the driving force of a black hole which is the strongest thing we know of
Looks like the intro to the monster of a B-movie,
Cool science? Give science a blanket :(
Well it depends on your point of view. Compared with most stuff you have at home, sulfuric acid is really strong (with a PKs of about 3). But compared with the stuff sitting around in most labs it is really pretty weak. Although you are right that it is technically classified as a strong acid. The real fun begins with hydrogen iodide or percloric acid (PKs = -10). And those are not even superacids. Check out HSbF6 (PKs = -17) (although I doubt that this one is sitting around in most labs)
We did this in my Chemistry class(:
You just made my day
Its because one of them had water in it, the powdered sugar had water in it. But the table sugar didn't. Instead it had potassium chlorate in it.
it looks like the beaker is pooping!! hahaha!!!
it depends how well the hydrogen dissociates
Recalling from High School Chemistry, sugar is C14,H22O11, or 14 carbon atoms and 11 water molecules, .
I didn't know Dan Aykryod was a chemist.
technically HF is a weak acid also. It will not dissociate in water very easily
Sulfuric acids applications are too many to count. It's used in all manner of industry. Very cool, and very dangerous too as we just saw.
cool video
pfft whatever, i think i'm right when it comes to sulfuric acid and any type of sugar opening up the gateway to hell, whether it be the bathroom or the fireplace
The acid is craving
I'm sure that was safe!
looks like one of my dookies after a mcdonalds.
Late-whatever gloves. I guess you could call that binomial nomenclature.
I use that for the bodies.
you're not wrong
1:27 Did she said "Howley Cow!"
i can smell it from here...lol
how concentrated was it?
oh, you mean that 1M solution is more corrosive than that 0.001M solution ?
MOM THE SUGAR POOPED !!!
HOLLY COW! lol
Next up, I think he should investigate the properties of fluoroantimonic acid - an acid that is 20 quintillion times more acidic than 100% sulfuric acid.
BigFoot Was Here...
Uhh, hydrofluoric acid isn't really a problem, because of fluorines electro-negativity it will "hold on" to the hydrogen atom that causes acids to be so reactive, therefore the reactivity of the halo acids would increase the further down the group, making the strongest obtainable hydroiodic acid, you might be able to use astatine but its radioactive and its rarer than gold.
no. as of now, the strongest acid known is fluoroantimonic acid, with a hammett acidity function of about -30. it is 20 quintillion times stronger than 100% sulfuric acid
I learned about this in school
isen't that the way the worm firework's work??
18 molar. 2 molar itself is enough to burn through concrete.
oh yes babe
cool science video lol
This is because you used Potassium Chloride not Potassium Chlorate. Potassium Chloride(KCl) is a salt whereas Potassium Chlorate(KClO3) is a powerful oxidizer. Some stump removers contain KClO3 so that's a possible source. If you're not familiar with the difference though you probably shouldn't be attempting this experiment yourself.
LOL Honestly your done having kids are you? 1:38 xD
I don't get it
he used sugar and sulfiric acid in both experiments but we got different reactions
how is that?
FIREWORK!
they STOLE my crap....those r my tiny ones tho
looks like the glass really had to poo
OHHHH the cup did a poo how beautiful
I Thought I-25 Was Near I Lived..? Jacksonville.. Florida?
I call it water... lol
We never did this at school. :(
My chemistry teacher did this in class :]
ok but, will it blend?
Oh crap the suger took a big poop!
The jar with sugar made chocolate bars and the one with match stuff in it had some really hot beens
By the way chocolate bars means poop
been a part of the internet for long?
stinks so good
He's talking about the smell and how babies poop.
very slow in downloading.
pooping upside down XD
I would love to see someone take an ordinary meal from any food joint and try to artificially make it into poop in a lab.
Maybe, but you gotta keep in mind that to turn graphite into diamonds, you need a lot of heat and a lot of pressure...it's not like you can just microwave it for a week and you will have diamonds. xD
You're done having kids right, lmfao.
1:26
Mmmm interesting.
No. Sulfuric acid is one of the weakest "strong" acids. The strongest acid would be Fluoroantimonic acid, which is the strongest "superacid".
now eat it!
Now you haven't seen Fluoroantimonic acid.
