Question

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

Options

A.

K

B.

Rb

C.

Li

D.

Na

Solution

Ionic mobility ∞1size of hydrated ion
Smaller size hydrated ion in aq. soln - Rb+(aq)
Larger size hydrated ion in aq. soln - Li+(aq)
Lowest ionic mobility in aq. soln → Li+(aq) due to high
hydration
