Vedclass · Answer

(B) The ease of adsorption of hydrated alkali metal ions on an ion-exchange resin depends on the size of the hydrated ion. Smaller alkali metal ions have a higher charge density,leading to greater hydration. Thus,the size of the hydrated ion follows the order: $Li^{+} > Na^{+} > K^{+} > Rb^{+}$. Since the ease of adsorption is inversely proportional to the size of the hydrated ion,the order of adsorption is: $Rb^{+} < K^{+} < Na^{+} < Li^{+}$.

The ease of adsorption of the hydrated alkali metal ions on an ion-exchange resins follows the order:
