The correct order of mobility of the alkali metal ions in aqueous solution is

Answer»

`Rb^(+)GTK^(+)gtNa^(+)gtLi^(+)`
`Li^(+)gtNa^(+)gtK^(+)gtRb^(+)`
`Na^(+)gtK^(+)gtRb^(+)gtLi^(+)`
`K^(+)gtRb^(+)gtNa^(+)gtLi^(+)`.

Solution :On the basis of explanation of ionic mobility extent of an ion GIVEN in Q. 24, the mobility of alkali metal ions in aqueous solution follows the order. `Rb^(+) GT K^(+) gt Na^(+) gt Li^(+)`.
