TheE(M^(3+)//M^(2+))^(@)values forCr,Mn,...

The`E_(M^(3+)//M^(2+))^(@)`values for`Cr,Mn,Fe andCo`are `0.41,+1.57,+0.77`and`+1.97`V respectively .For which one of these metal the change in oxidation state from`+2`to`+3`is easiest:

A

Fe

B

Mn

C

Cr

D

Co

Text Solution

Verified by Experts

The correct Answer is:
C

As Cr has maximum oxidation potential value, therefore its oxidation should be easiest.
