Why BaSO_(4) is insoluble whereas BeSO_(4) is soluble in water ? |
| Answer» Solution :The lattice enthalpy of `BaSO_(4)` is MUCH than its hydration enthalpy and hence it is INSOLUBLE in WATER . But on, the other hand , hydration enthalpy of `BeSO_(4)` is much higher than its lattice enthalpy because of small size of `Be^(2+)` ions . THEREFORE , it is HIGHLY soluble in water . | |
