Zine can be coated on iron to produce galvanize3d iron but the reverse is not possible it is because

A

Zinc has higher negative electrode potential than iron

B

Zinc is lighter than iron

C

Zinc has lower melting point than iron

D

Zinc has lower negative electrode potential than iron

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(Zn^(+2)//Zn)^(@)= -0.76V, E_(Fe^(+2)//Fe)^(@)= -0.44V`
Zn has higher negative SRP (standard reduction potential) so it work as anode and protect iron to make iron as cathode
