Potassium Chlorate from Bleach

Today I'll be making potassium chlorate from bleach. It's a very simple procedure, but the tradeoff is that it isn't very efficient. Electrolysis is a better method, and I'll visit that in a later video.

Here's the procedure. Start with 500mL of regular old bleach, and boil it down until crystals just start forming. Remove from heat, and let cool. Prepare a saturated solution of potassium chloride that is the same volume as the boiled bleach solution. Add the two together, and crystals of KClO3 should precipitate. If they don't, refrigerate the solution. Even if you do get immediate precipitation, cooling the solution will increase your yield.
