Vedclass · Answer

(C) Ionic mobility is inversely proportional to the size of the hydrated ion: $	ext{Ionic mobility} \propto \frac{1}{	ext{size of hydrated ion}}$.In aqueous solution,the extent of hydration depends on the charge density of the ion.Smaller alkali metal ions have higher charge density,leading to greater hydration.The order of hydrated ionic size is: $Li^{+}_{(aq)} > Na^{+}_{(aq)} > K^{+}_{(aq)} > Rb^{+}_{(aq)}$.Since $Li^{+}$ has the largest hydrated size,it experiences the most drag in an electric field.Therefore,$Li^{+}$ has the lowest ionic mobility.

Ionic mobility of which of the following alkali metal ions is lowest when aqueous solution of their salts are put under an electric field?
