sulfuric acid plus potassium chlorate yields what?

I read that when adding sulfuric acid slowly to potassium chlorate it gives me potassium perchlorate, in another website I read that when adding sulfuric acid to potassium chlorate it gives me potassium sulphate and chloric acid?

Please if you have any information about this, help me.

Thank you.

Chlorates are extremely unstable, if the pH is low enough, which you achieve with adding sulfuric acid [affil links], the chlorate will disproportionate and form perchlorate and chloride.

Sounds like you know enough chemistry to be dangerous. These compounds are not at all friendly. Adding H₂SO₄ to KClO₃ can lead to a very bad day for the person playing chemist.

Ed. note: The internet is a one-room schoolhouse, with post-doctorates and elementary school children reading the same pages, as well as people for whom English may be a second or third language. So, in case Trent wasn't clear, he is saying that only trained chemists should be attempting any such experiments.

I never would try to do such kind of reactions, without knowing a secure process for doing them. I like my fingers, eyes and all other parts of my body and want to keep them . From my knowledge, this kind of reaction is used to manufacture perchlorate, starting from Hypochloric salts.

By the way it is the same kind of reaction which produces chlorine gas when you use sodium hypochlorite to oxidize cyanides, and then add acid to lower the pH, before reducing the excessive sodium hypochlorite.

Ah, oh Ah !

When I first saw this 'inquiry' I thought that Student Waleed Battar was thinking of making some explosives, cheaply, mind you.

Waleed, you really should try to put some red phosphorus with your chlorate. Most impressive. Guaranteed that you'd never ever (be able to) contact fin.com again.

I did it once with some damp chlorate, a teaspoonful, + some small particles of red phosphorus. I walked for 6 paces and then BANG ... ruined a new sweater and scared the hell out the neighbors. Since then I've been on Valium.

this question is mine too! and I'm seeking the answer but I know that the product is not Cl₂ and people who say one of the products is Cl₂ are wrong.
I hope it can help.
