Copper(I) oxide Wikipedia
Copper(I) oxide may be produced by several methods. Most straightforwardly, it arises via the oxidation of copper metal: 4 Cu + O 2 → 2 Cu 2 O. Additives such as water and acids affect the rate of this process as well as the further oxidation to copper(II) oxides.Get Price
