Current Question (ID: 7992)

Question:

$\text{Which of the following compounds has a higher hydration energy than the lattice energy?}$

Options:

1. $\text{BaSO}_4$ (Correct)
2. $\text{MgSO}_4$
3. $\text{CaSO}_4$
4. $\text{SrSO}_4$

Solution:

$\text{Hydration energy depends on the size of ion.} \text{Hydration energy of sulphate decreases from top to bottom in a II}^{nd} \text{ group. Mg}^{2+} \text{ is smaller in size than other ions of that group. So, Mg}^{2+} \text{ ion is readily hydrated.} \text{MgSO}_4 \text{ has higher hydration energy than lattice energy.}$
