Question

Describe cathodic protection of metals from corrosion.

Answer 1

Cathodic protection of metals:

1. The method of cathodic protection is used to control corrosion of the metals.
2. It is usually done by making the metal into a cathode of the electrochemical cell.
3. In this method an anode is made of sacrificial metal. This metal gets corroded instead of the metal (cathode).
4. This is used for making long pipeline structures, and steel storage tanks.
