The standard reduction potentials of Fe^...

The standard reduction potentials of `Fe^(3+)//Fe " and "Fe^(2+)//Fe` electrode system are -0.035 V and -0.44 V respectively. Predict which of the two oxidations is easy. `Fe^(3+)//Fe " and " Fe^(2+)//Fe`.

Text Solution

Verified by Experts

(i) The ion which has lower reduction potential will be oxidised first at the anode.
(ii) Among (0.035V) and (0.44V), `Fe^(2+)//Fe` oxidation is easy because it has the lower reduction potential (-0.44V).
