As we know that hydration power decreases on moving down the group hence among alkali metals Li has excessive hydration hence it has low mobility in aqeous solution.

Q. In the given below alkali metal ions which has lowest ionic mobility in aqueous solutions?

$R b^{+}$

$C s^{+}$

$L i^{+}$

$N a^{+}$

As we know that hydration power decreases on moving down the group hence among alkali metals Li has excessive hydration & hence it has low mobility in aqeous solution.
