What happens when copper undergoes oxidation?

Just as iron that is left unprotected in open air will corrode and form a flaky orange-red outer layer, copper that is exposed to the elements undergoes a ... In fact, the weathering and oxidation of the Statue of Liberty's copper skin has amounted to just . read more

When copper is oxidised it loses electrons to form Cu2+. This then bonds to an O2- anion to form copper oxide CCuO. read more

On the product side, copper is in the form of Copper nitrate, i.e., Cu(NO3)2. Here, Cu has the oxidation state of +2 (Cu2+). So, in the above reaction, Cu changes to Cu2+, i.e., there is an increase in the oxidation state => OXIDATION OF COPPER. read more

When oxidation and reduction occur simultaneously, they are called oxidation-reduction, or redox, reactions. Oxidation happens constantly. Sometimes it is destructive, while other times it is useful. Oxidation happens spontaneously, but sometimes it is induced by humans for cleaning, sterilizing, or laboratory purposes. read more
