What happens when copper oxide reacts with water

Copper (I) Oxide can react with water as oxygen is present and make Copper (II) Hydroxide. Copper oxide acts as a weak base because when dissolved in water, it produces mild basic hydroxide Cu (OH)2. Copper oxidizes slowly in the air, corroding to produce a brown or green patina. At higher temperatures, the process is much faster and produces mainly black copper oxide. Hydrogen gas, a moderately strong reducing agent, can reduce the oxide, producing a shiny, clean copper surface. Hand Protection: Wear if skin contact is probable and skin is sensitive. Eye Protection: Safety glasses or goggles. Skin Protection: Long sleeve shirt(s) if contact is probable and skin is sensitive. Environmental Protection: Do not allow to enter drains or watercourses.

Copper oxide (CuO) nanoparticles (NPs) are among the most widely used engineered NPs and are thus likely to end up in the environment, predominantly in sediments. Copper oxide NPs are toxic to various (mainly pelagic) organisms but to differing degrees. Compared to Cu2O, CuO is a more thermally stable material because of the stability of CuO with a high oxidation number. When Copper is exposed to water molecules (two hydrogens, one oxygen), this free electron is transferred to a neighbouring oxygen atom, bonding it into a molecule. If only one atom of copper bonds to an oxygen molecule, it is called cupric oxide. The most common forms of copper oxide are Copper (I) oxide and copper (II) oxide. These forms of copper oxide and other forms are formed when oxygen combines with Copper in different ways. Copper (I) oxide is a reddish powder, whereas Copper (II) oxide is a black powder.
