Vedclass · Answer

(D) The stability of $Cu^{2+}_{(aq)}$ is more than $Cu^{+}_{(aq)}$ is due to the much more negative $\Delta_{hyd}H^{\circ}$ of $Cu^{2+}_{(aq)}$ than $Cu^{+}_{(aq)}$,which more than compensates for the second ionisation enthalpy of $Cu$.$\Delta_{hyd}H^{\circ}$ of $Cu^{2+}_{(aq)} = -2121 \ kJ \ mol^{-1}$$\Delta_{i}H_{1}^{\circ}$ of $Cu = +745 \ kJ \ mol^{-1}$$\Delta_{i}H_{2}^{\circ}$ of $Cu = +1960 \ kJ \ mol^{-1}$

The stability of $Cu^{2+}$ is more than $Cu^{+}$ salts in aqueous solution due to -
