The hydration entahphy of `Mg^(2+)` ion is higer than that of

A

`Al^(3+)`

B

`Na^(+)`

C

`Be^(2-)`

D

`Mg^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
Hydration energy depends on charge of ion and ionic radius. Higher the charge, greater the hydration energy. On the other hand, smaller the size, greater the hydration energy. Charge is considered first for comparison. Hence, `Mg^(2+)` has higher hydration energy than `Na^(+)`.
