Question

Which of the following alkali metal ions has the lowest ionic mobility in aqueous solutions?
A. `Li^(o+)`
B. `Na^(o+)`
C. `K^(o+)`
D. `Cs^(o+)`

Answer 1

Correct Answer - D
Although charge density of `Li^(o+)` is maximum so it is extensively hybrated and its ionic molility is least and that of `Cs^(o+)` is highest .
