The ionic mobility of alkali metal ions is aqueous solution is maximum for (RPMT 2010)
A.K⁺
B.Rb⁺✓ Correct
C.Li⁺
D.Na⁺
Explanation
The ionic mobility of alkali metals in the aqueous solution is directly proportional to the atomic size. The atomic size increases down the group and it decreases from left to right in a period. Therefore, Rubidium ion has the highest ionic mobility as it has a large atomic size.
