Solubility of the alkaline earth's metal sulphates in water decreases in the sequence :
The solubility of the alkaline earth's metal sulphates in water decreases in the sequence $$Mg > Ca > Sr > Ba$$.
With the increase in the cationic size on moving down the group, the extent of the hydration of the cation decreases. However, the decrease in the lattice energy with increase in cationic size is small.
Thus, the decrease in hydration energy is more significant than the decrease in lattice energy. Hence, the solubility of the alkaline earth's metal sulphates in water decreases on moving down the group.
