Zinc can be coated on iron to produce galvanometer is reverse is not possible. It is because

A

Zinc has lower negative electrode potential

B

Zinc has higher negative electrode potential

C

Zinc is lighter than iron

D

Zinc has lower melting point than iron.

Text Solution

Verified by Experts

The correct Answer is:
B
Zn have a higher (-ve) electrode potential that reactive than Fe. It is coated on iron provide resistance against rusting such a process is galvanisation. But in reverse, that is Fe cannot be Zn, as corrosion will occur. In above, Zn dissolved in its solution.
