Products Description of Cupric oxide CAS#1317-38-0

Copper oxide is an inorganic substance with the chemical formula CuO. It is a black oxide of copper, slightly amphoteric and slightly hygroscopic. Insoluble in water, easily soluble in acid, stable to heat, and decomposes into oxygen at high temperatures. It can be reduced to metallic copper by introducing hydrogen or carbon monoxide at high temperature. Copper oxide is heated in Chemicalbook air and releases oxygen at about 1050°C and is reduced to cuprous oxide. If it is in hydrogen or carbon monoxide gas flow, it can be easily reduced to metallic copper even at temperatures below 250°C. Although copper oxide is insoluble in water, it is soluble in aqueous alkali metal hydroxide solutions.
