Copper (II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or copper (I) oxide (cuprous oxide). As a mineral, it is known as tenorite, or sometimes black copper.

Cupric oxide, or copper (II) oxide, is an inorganic compound with the chemical formula CuO. Cupric oxide is used as a precursor in many copper-containing products such as wood preservatives and ceramics. Cupric oxide may be found in over-the-counter vitamin-mineral supplements as a source of [DB09130].

Cupric oxide is an inorganic chemical compound composed of cuprous ion and oxide ion. Cupric cuprous are the two forms of copper ions. Copper exists in two types of oxide, the one is with a higher oxidation state and another one is with a lower oxidation state, cupric oxide and cuprous oxide respectively. The oxides of copper are of two types:

2022年8月16日 · Cupric oxide readily dissolves in mineral acids such as sulfuric acid, nitric acid and hydrochloric acid to give the corresponding copper (II) salts (copper sulfate, nitrate and chloride respectively).
