There are frequent references in the literature to the decomposition of hypochlorite solutions on keeping or by heating, and to their decomposition by light. The first mention of their decomposition by metallic oxides is by Balard (1) who observed that in the presence of silver oxide hypochlorites are decomposed with evolution of oxygen. Gay Lussac (2) found a similar decomposition in the presence of powdered pyrolusite, and this was confirmed by Mitscherlich (3). Fleitmann (4) suggested warming hypochlorite solutions with the oxides of cobalt, nickel, copper or iron as a means of preparing oxygen, and Bidet (5) described a method of obtaining a continuous stream of oxygen by the action of cobalt oxide on bleaching powder. Böttger (6) has examined the action of barium peroxide.
