WARNING! This experiment is dangerous! You should NOT perform this at home. ONLY carry out this experiment, if you are a trained chemist, and you understand local safety and legal requirements, which are required to perform such experiments
- Pour about 500 ml of bleach into a thermo resistant beaker and boil it on a hotplate to get rid of most of the water.
- When crystals start to appear in the solution, cool it down. These are sodium chloride crystals.
- Filter the solution. The Remaining solution contains sodium chlorate and the remainder of sodium chloride.
- Prepare a saturated solution of potassium chloride. The Volume of this solution should be equal to the boiled bleach solution.
- Mix together the two solutions. Potassium chlorate crystals should precipitate in the solution.
- If there are no crystals in the solution cool it down in a fridge.
