Given`E^(c-)._(Ag^(o+)|Ag)=+0.80V,E^(c-)._(Co^(2)|Co)=-0.28V, E^(c-)._(Cu^(2+)|Cu)=+0.34V,E^(c-)._(Zn^(2+)|Zn)=-0.76V`
Which metal will corrode fastest ?

A

`Ag` will oxidize to `Ag^(o+)` and new `[Ag^(o+)]=1.36M`.

B

`Cu`

C

`Co`

D

`Zn`

Text Solution

Verified by Experts

The correct Answer is:
d
Corrosion`:` Metal gets oxidized . `E^(c-)._(Zn^(2+)|Zn)` is most negative.
