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. |

Answer» Solution :(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). |
