Comment on the following observationThe mobility of alkali metal ions

1.	Comment on the following observationThe mobility of alkali metal ions in aqueous solution Is Li^+ lt Na^+ lt K^+ lt Rb^+
Answer» SOLUTION :A SMALLER ion is HEAVILY HYDRATED which MAKES it sloe moving.Hydration varies in the order `Li^+ gt Na^+,K^+.Rb^+ gt Cs^+` and hence mobillty is in the reverse order.
