Cobalt (III) oxide is the inorganic compound with the formula of Co2O3. Most commonly used in bleach. Although only two oxides of cobalt are well characterized, CoO and Co3O4,[3] procedures claiming to give Co2O3 have been described. Thus treatment of Co(II) salts such as cobalt(II) nitrate with an aqueous solution of sodium hypochlorite (also known as bleach) gives a black solid.[4] Some formulations of the catalyst hopcalite contain "Co2O3".
