What Are the Reasons of Copper Oxidization?
The process of oxidization is familiar to us. A reddish brown flaky layer is produced by iron, white flakes are produced by aluminum, air and moisture makes apple turn brown for some time. Just like this, copper also oxidizes. As iron turns rust when exposed to air and moisture during oxidization, copper changes to green when exposed to oxygen. In this case, water is not necessary for oxidization of copper and it does not even react with water. From peachy pink to green The original color of copper is pink or peachy with a metallic shine. Only oxidization can make it turn green. The question arises that why copper turn green when oxidized. During the process of oxidation, the elements lose electrons that are usually hydrogen while reacting with other elements. In this case, copper reacts with oxygen forming copper oxide which is of green color. A coating is formed on the surface that is called copper patina. A protective layer around the copper is actually formed by the patina. Further
