Which of the following alkaline earth metal sulphates has its hydratio

1.	Which of the following alkaline earth metal sulphates has its hydration enthalpy greater than its lattice enthalpy ?
Answer» `BaSO_(4)` `SrSO_(4)` `CaSO_(4)` `BeSO_(4)` SOLUTION :Among alkaline earth METAL SULPHATES , lattice enthalpy remains almost constant but HYDRATION enthalpy decreases down thegroup . Thus , `BeSO_(4)` has higher hydration enthalpy as compared to lattice enthalpy .
