Vedclass · Answer

(B) The degree of hydration is directly proportional to the charge density or ionic potential of the ion,which is defined as the ratio of charge to ionic radius $(q/r)$.As we move down the group from $Li^{+}$ to $Cs^{+}$,the ionic radius increases,which leads to a decrease in the charge density.Therefore,the hydration energy and the degree of hydration decrease as the size of the ion increases.The correct order of relative degree of hydration is: $Li^{+}_{(aq)} > Na^{+}_{(aq)} > K^{+}_{(aq)} > Rb^{+}_{(aq)} > Cs^{+}_{(aq)}$.
