What is Oxidized Copper? Definition from Corrosionpedia

Copper, when exposed to the atmosphere, will become oxidized due to a reaction with oxygen. The reaction takes place when water or moisture in the air comes into contact with copper. The basic reaction of copper with the oxygen in the atmosphere, which converts copper to copper oxide is as follows: 2 Cu(s) + O 2 (g) > 2 CuO(s)
