प्रश्न
Why are BeSO4 and MgSO4 readily soluble in water while CaSO4, SrSO4 and BaSO4 are insoluble?
उत्तर
The hydration enthalpies of BeSO4 and MgSO4 are quite high because of small size of Be2+ and Mg2+ ions. These hydration enthalpy values are higher than their corresponding lattice enthalpies and therefore, BeS04 and MgSO4 are highly soluble in water. However, hydration enthalpies of CaSO4, SrSO4 and BaSO4 are not very high as compared to their respective lattice enthalpies and hence these are insoluble in water.
