Vedclass · Answer

(B) The solubility of sulphates of alkaline earth metals decreases down the group due to the decrease in hydration energy being more significant than the decrease in lattice energy as the cationic size increases. The order is $BeSO_4 > MgSO_4 > CaSO_4 > SrSO_4 > BaSO_4$.$Na_2SO_4$ is an alkali metal sulphate and is highly soluble in water compared to alkaline earth metal sulphates.Therefore,the correct order of solubility is $Na_2SO_4 > BeSO_4 > MgSO_4 > BaSO_4$.

The solubility of $Na_2SO_4$,$BeSO_4$,$MgSO_4$ and $BaSO_4$ in water follows the order:
