Cobalt(III) oxide is the inorganic compound with the formula Co2O3. Although only two oxides of cobalt are well characterized, CoO and Co3O4,[3] procedures claiming to give Co2O3 have been described involving treating cobalt(II) nitrate with an aqueous solution of sodium hypochlorite (also known as bleach). The product is a black solid.[4]
