Using the `E^(@)` values of A and B predict which is better for coating the surface of iron ` [E_ ((Fe^(2+)//Fe))^(@) =-0.44V]` to prevent corrosion and why ?
`E_((A^(2+)//A))^(@)=-2.37V`, `E_((B^(2+)//B))^(@)= 0.14V`

Text Solution

Verified by Experts

A will prevent iron from rusting , So , we can coat the iron surface with metal A because it has more negative value.
