Cupric Oxide / Cuprous Oxide Description:

 a) Copper oxide can refer to:

  Copper(I) oxide (cuprous oxide, Cu2O), a red or brown powder

  Copper(II) oxide (cupric oxide, CuO), a black powder.

 b) Compounds containing univalent copper are frequently referred to as "cuprous" compounds. The more common compounds of copper are those in which the metal is bivalent or "cupric" compounds
