`BaSO_4` is insoluble in water, but `BeSO_4` is soluble in water-Explain.

Text Solution

Verified by Experts

The lattice enthalpy of `BeSO_4` is much higher than its hydration enthalpy and hence, it is insoluble in water. On the other hand, the hydration enthalpy of `BeSO_4` is much higher than its lattice enthalpy because of loose packing of small Be2t ion with the relatively large sulphate ion. Hence, it becomes soluble in water.
