Vedclass · Accepted Answer

$MgSO_4$

Vedclass · Answer

(A) The hydration energy of sulphates decreases as we move down the group $II$ in the periodic table.$Mg^{2+}$ is the smallest ion among the group $II$ alkaline earth metal ions,which results in a very high charge density.Due to its small size,the hydration energy of $Mg^{2+}$ is significantly high,making it greater than its lattice energy.As a result,$MgSO_4$ is highly soluble in water,whereas the solubility of other sulphates like $SrSO_4$ and $BaSO_4$ decreases due to their lattice energy being higher than their hydration energy.

In which of the following is the hydration energy higher than the lattice energy?
