The ionic mobility of alkali metal ions in aqueous solution is maximum for
A.
$$L{i^+}$$
B.
$$N{a^ + }$$
C.
$${K^ + }$$
D.
$$R{b^ + }$$
Answer :
$$R{b^ + }$$
Solution :
Smaller the size of cation higher is its hydration energy and greater is its ionic mobility hence the correct order is $$L{i^+} < N{a^ + } < {K^ + } < R{b^ + }$$
