The ionic mobility of alkali metal ions in aqueous solution is maximum for
The ionic mobility of alkali metal ions in aqueous solution is maximum for
Open in App
Solution
The correct option is A
Smaller size of the ion, more is the extent of hydration and consequently lesser is the mobility. Ion has largest size and therefore, its hydration will be less. As a result, its effective size will be smaller and hence maximum ionic mobility in aqueous solution.
