Potassium chlorate Potassium chlorate Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO. In its pure form, it is a white crystalline substance. It is the most common chlorate in industrial use. It is used On the industrial scale, potassium chlorate is produced by the Liebig process: passing chlorine into hot calcium hydroxide, subsequently adding potassium chloride: The electrolysis of KCl in aqueous solution is also used sometimes, in which elemental chlorine formed at the anode react with KOH "in situ". The low solubility of KClO in water causes the salt to conveniently isolate itself from
