In the following question two or more options may be correct.
Which of the following compounds are readily soluble in water?
Out of the given compounds, BeSO4 and MgSO4 are readily soluble in water. The solubility of the sulphates decreases from CaSO4 to BaSO4. The compounds are readily soluble because the greater hydration enthalpies of Be2+ and Mg2+ ions overcome the lattice enthalpy factor.
