Question

difference between corrosion of iron and corrosion of aluminium​

Answer 1

Answer:

Iron and steel rust when they come into contact with water and oxygen. They rust faster in salty water or acid rain. Aluminium, on the other hand, does not corrode easily, because its surface is protected by a layer of aluminium oxide.

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.
