For Galvanizing Iron which of the following Metals is used?
A)
Lead
B)
Copper
C)
Zinc
D)
Aluminium

Correct Answer : Option (C) - Zinc



The process of applying a coating of zinc (Zn) on iron or steel to protect it from rusting is called galvanising or galvanizing iron.

Zinc is also called sacrificial anode. The process is called cathodic protection. If zinc is scratched or corroded, it will continue to protect the iron from oxidation electrochemically. Tin also protects iron from rusting. But when it is worn away, it accelerates rusting instead of protecting it.
