Zinc is coated over ion iron to prevent rusting of iron because :

A

`E_(red)^(@)` of zinc is greater than that of Fe

B

`E_(ox.)^(@)` of Zn is greater than that of Fe

C

`E_(red)^(@)` of Zn is nearly equal to that of Fe

D

Zn is cheap

Text Solution

Verified by Experts

The correct Answer is:
B
`E_(o x)^(@)` of Zn is greater than that of Fe hence zinc will protect Fe from rusting by a process caled galvanisation.
