Make Potassium Chlorate from Bleach

How to Make Potassium Chlorate from Bleach and sodium-free salt.

Warning: This produces small amounts of chlorine gas, this should be done outside or in a fumehood.

Potassium chlorate is a useful oxidizer and small amounts can be easily made using household chemicals. Start by boiling a large quantity of household laundry bleach, at least half a liter, until crystals start to precipitate. Immediately take it off heating and let it cool. As it cools make a saturated solution of potassium chloride. Potassium chloride is sold as a "sodium-free" salt substitute. Now once the bleach is cooled, measure out an equal volume of potassium chloride solution and pour into the boiled bleach solution but do not mix in the crystals. Stir up the mixture and eventually potassium chlorate crystals will precipitate out.

What's happening is the sodium hypochlorite in the bleach is disproportionating to form sodium chloride and sodium chlorate. Adding the potassium chloride exchanges the ions and precipitates out potassium chlorate.

The boiling is required for this reaction to work; you can't simply let the bleach evaporate.

Make the damn electrolysis

[mcwario13]

you haven't made it with electrolysis yet , so make it!!!

[sekterboy9]

my salt substitute contains nh4cl. is there any problem (with the formation of nh4clo3)? how could i get the nh4cl out of my salt?

@nikola96uf that happened to me too

Why would anyone care about an electrolysis? This is much easier, and cheaper, and actually possible.

What do you use this stuff for?

HEY NurdRage have you any idea of how to make potassium perclorate

@DocteurDuCube Thank you!

[DocteurDuCube]

@Iodstickstoff Yes, bleach is 'eau de Javel'

[kalkbayrock]

my solution went pink? does anyone know why?

Can you make a vide on how to make Ammonium perchlorate?
