Aluminium chlorate, Al(ClO₃)₃

Aluminium chlorate, Al(ClO₃)₃.9H₂O, prepared by mixing aluminium sulphate and barium chlorate, removing the barium sulphate, and evaporating the cold solution over sulphuric acid, is very soluble in water. From a hot solution it separates as the hexahydrate. The salt is easily decomposed by heat, and explodes when slowly heated.
