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

1.	The ionic mobility of alkali metal ions in aqueous solution is maximum for
Answer» `K^(+)` `Rb^(+)` `Li^(+)` `Na^(+)`. SOLUTION :Bigger the SIZE, LOWER is the extent of hydration THEREFORE, smaller is the size of the hydrated species and highest is the ionic MOBILITY, i.e., `Rb^(+)` has the maximum mobility .
