Cupric Oxide/Copper Oxide (CuO) is the higher oxide of copper. As a mineral, it is known as tenorite. It is a black solid with an ionic structure which melts above 1200 °C with some loss of oxygen. It can be formed by heating copper in air. Copper(II) oxide is a amphoteric oxide, so it dissolves in mineral acids such as hydrochloric acid, sulfuric acid or nitric acid to give the corresponding copper(II) salts.



Property: black to brown amorphous powder or crystalline particles (monoclinic crystals). Relative density 6.315, melting point 1446 °C, Mohs hardness 3-4, dielectric constant 18.10, insoluble in water, soluble in acid, ammonia, ammonium chloride, dissolved in sodium hydroxide to produce blue color solution, which leads to hydrogen or carbon monoxide at high temperature.
