Which one of the following ions has highest limiting molar conductivit

1.	Which one of the following ions has highest limiting molar conductivity?A. `Na^(+)`B. `Mg^(2+)`C. `K^(+)`D. `Ca^(2+)`
Answer» Correct Answer - D Ion `Na^(+)K^(+)Mg^(2+)Ca^(2+)` 50-70 73.50 106.0 119.0 `^^_(m)^(@)` `(S cm^(2)"mol"^(-1))` The size of hydrated `Na^(+)` ion is largest and that of `Ca^(2+)` is the smallest. Hence they follow the above order.
