Perchlorate

 

any salt of perchloric acid (HClO4). A perchlorate is colorless if its cation is colorless. Perchlorates dissolve freely in water, except potassium perchlorate (KCIO4), whose slight solubility is only 1.3 g per 100 g H2 O at 25°C. They are stable when heated to temperatures between 300° and 600°C; at higher temperatures they decompose and release oxygen, as in the reaction KCIO4 = KCl + 2O2. Among the methods for obtaining perchlorates are heating of chlorates and electrolysis of chlorate solutions. Perchlorates are used to make safety explosives; for example, KCIO4 is a stronger oxidizing agent than potassium chlorate (KCIO3) and is suitable for storage, since it does not explode upon friction or impact.
