Vedclass · Answer

(D) The stability of a metal ion in an aqueous solution depends on the balance between the energy required to form the ion (sum of enthalpy of atomization and ionization energy) and the energy released during hydration (hydration enthalpy). Specifically,the electrode potential $(E^\circ)$ is determined by the sum of these energy terms: $E^\circ = \Delta_{sub}H + \Delta_{ion}H + \Delta_{hyd}H$. Therefore,all these factors contribute to the stability of the oxidation state in an aqueous medium.

The stability of a particular oxidation state of a metal in an aqueous solution can be determined by:
