Reaction of Sulfuric Acid and Sugar
Loading...
Uploaded by vaskopp93 on May 8, 2010
One of the most spectacular chemistry demonstrations is also one of the simplest. It's the dehydration of sugar (sucrose) with sulfuric acid.
Sugar is a carbohydrate, so when you remove the water from the molecule, you're basically left with elemental carbon. The dehydration reaction is a type of elimination reaction.
C12H22O11 (sugar) + H2SO4 (sulfuric acid) → 12 C (carbon) + 11 H2O (water) + mixture water and acid
Although the sugar is dehydrated, the water isn't 'lost' in the reaction. Some of it remains as a liquid in the acid. Since the reaction is exothermic, much of the water is boiled off as steam.

@punishedexistence Oh and by the way I am *not* smart. I just learned the hard way!!

Yes there is inhibitors in drain cleaner. I did the same thing earlier today with paper towels in a soup can, it takes a bit longer but the reaction is every bit as violent. Even dilute sulfuric acid is a hell of a dehydrating agent. It's all fun till you splash it on yourself. Luckly I have never spilled more than a drop or two on me, and I went through 4 and a half years of organic chemistry classes. I was smart. You get that shit on your skin and you are fucked. Worse than nitric acid.

I was hoping that it might explode

big turd
-
fact:pure sulphuric acid doesnt react with most things as its heavily hydrogen bonded
-
i thibk you shoul wear a glove. your hand is the same as sugar
-
Can I eat it? :3

Quit complaining about the color and saying its fake. I know that this is sulfuric acid drain cleaner. I have some and did this. They put inhibitors in it so you have time to get it off your hand. Why does it matter if its 'pure' anyways? It is still sulfuric acid. Purity doesn't change its chemical formula. Most sulfuric acid is only 98% pure anyways. Just enjoy the video and quit complaining about it.

People posting here that sulfuric acid is colourless clearly don't do chemistry.
Sulfuric acid is colourless when in a solution. When it is more concentrated/not dissolved it's a pale yellow colour, and isn't a liquid.
Also this is the exact reaction between table sugar and sulfuric acid:
H2SO4( + C12H22O11 → 12 C + 11 H2O (and H2O + SO3 due to heat)
The black stuff here is the Carbon.
