D
Text Solution
Verified by ExpertsThe correct answer is:
A
When hydration energy exceeds lattice energy, the compound becomes soluble in water. The solubility of alkaline earth metal sulphates decreases in the order:
very high | high | Sparinglysoluble | almost insoluble |
The solubilities of 
and 
are due to high energy of solvation of smaller 
and 
ions.
