Question

compare corrosion of Cu with corrosion of Fe

Answer 1

Answer:

corrosion of iron

Remember that technically only iron and alloys that contain iron can rust.

Compared to the corrosion of other metals, iron rusts relatively quickly, especially if it is exposed to water and oxygen. In fact, when iron is exposed to water and oxygen, it can begin to rust within a few hours.

Iron will also rust quickly if it’s exposed to high temperatures. Extreme temperatures can alter the metal’s chemical makeup, which makes it extremely prone to recombining with oxygen in the environment.

corrosion of copper                        

Copper does not rust, however, it does corrode. Copper is naturally brown and turns a shade of bright green as it corrodes. While some consider copper’s reaction to be tarnish rather than oxidation, the metal still undergoes a similar “rusting” process.

When a metal is atacked by its surrounding air , moisture , acid etc it is said to be corroded . The process is called corrosion.

Electrochemical corrosion of metals occurs when electrons from atoms at the surface of the metal are transferred to a suitable electron acceptor or depolarizer. Water must be present to serve as a medium for the transport of ions.
