Question

in electrochemical corrosion of metals, the metal undergoing corrosion is​

Answer 1

Answer:

In electrochemical corrosion. the metal undergoing corrosion acts as an anode. In anode region, the metal is oxidized to metal cation and in cathode region, oxygen is reduced to water.

Answer 2

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. The most common depolarizers are oxygen, acids, and the cations of less active metals.

Causes of Corrosion

Causes of Corrosion Metal corrodes when it reacts with another substance such as oxygen, hydrogen, an electrical current or even dirt and bacteria. Corrosion can also happen when metals like steel are placed under too much stress causing the material to crack.
