S Block Elements

Question

The correct order of the solubility of alkaline-earth metal sulphates in water is :

Accepted Answer

Option D. The solubility of the sulphates in water decreases down
the group. Mg > Ca > Sr > Ba. MgSO₄
 is soluble, but
CaSO₄ is sparingly soluble, and the sulphates of Sr, Ba and Ra are virtually insoluble. The significantly high solubility of MgSO4 is due to the high enthalpy of solvation
of the smaller Mg²⁺ ion.
