Question
The ease of adsorption of the hydrated alkali metal ions on an ion-exchange resins follows the order:
Options
A.Na+ < Li+ < K+ < Rb+
B.Li+ < K+ < Na+ < Rb+
C.Rb+ < K+ < Na+ < Li+
D.K+ < Na+ < Rb+ < Li+
Solution
Greater the size of the hydrated ion, more will be the surface area and more will be its ease ofadsorption.
