Vedclass · Answer

(B) In aqueous solutions,ions are hydrated. The extent of hydration is inversely proportional to the size of the ion. Smaller ions have higher charge density,leading to greater hydration and a larger hydrated radius. Thus,the order of hydrated ionic size is $Na^{+} > K^{+} > Rb^{+} > Cs^{+}$. Since ionic mobility is inversely proportional to the hydrated size,the order of ionic mobility is $Cs^{+} > Rb^{+} > K^{+} > Na^{+}$.
