The sequence of ionic mobility in aqueous solution is

1.	The sequence of ionic mobility in aqueous solution is
Answer» `Rb^(+)gt K^(+) gt Cs^(+) gt Na^(+)` `Na^(+) gt K^(+) gt Rb^(+) gt Cs^(+)` `K^(+) gt Na^(+) gt Rb^(+) gt Cs^(+)` `Cs^(+) gt Rb^(+) gt K^(+) gt Na^(+)` Solution :Bigger the size , lower is the extent of HYDRATION , smaller is the mass of the hydrated SPECIES and hence HIGHER is the ionic mobility in the aqueous solution . Thus OPTION (d) is correct .
