Sulphates of Be and Mg are readily soluble in water but sulphates of Ca, Sr and Ba are insoluble. This is due to the fact.
A
The greater hydration enthalpies of

Text Solution
Verified by ExpertsThe correct answer is:
A
Due to smaller size their lattice enthalpies are high but their greater hydration enthalpies overcome the lattice enthalpies and they become soluble in water. Ca, Sr and Ba sulphates are insoluble in water due to lower hydration enthalpies.
