Potassium Hypochlorite Formula

Potassium hypochlorite with the formula KClO is a pungent colourless solution with an irritating odour. Potassium hypochlorite can be prepared by the reaction of chlorine with potassium hydroxide. It can also be produced by the electrolysis of potassium chloride solution. In both methods, the reaction mixture must be kept cold to prevent the formation of potassium chlorate. In this article, we shall learn more about the potassium hypochlorite formula, its chemical structure, properties and uses.
