Vedclass · Answer

(D) In aqueous solution,alkali metal ions are hydrated. The extent of hydration is inversely proportional to the ionic size. Smaller ions have higher charge density and thus get more hydrated,resulting in a larger hydrated radius.Since ionic mobility is inversely proportional to the size of the hydrated ion,the hydrated radius order is $Li^{+} > Na^{+} > K^{+} > Rb^{+}$.Therefore,the ionic mobility order is $Li^{+} Thus,the ionic mobility is maximum for $Rb^{+}$.

The ionic mobility of alkali metal ions in aqueous solution is maximum for
