Q. Which of the following sulphates has the highest solubility?
A) ${BeSO}_{4}$
B) ${MgSO}_{4}$
C) $BaSO_{4}$
D) ${CaSO}_{4}$
Explanation
(a)
${BeSO}_{4}$ is most soluble because hydration energy is more than lattice energy
${BeSO}_{4} > {MgSO}_{4} > {CaSO}_{4} > {SrSO}_{4} > {BaSO}_{4}$
Hydration energy decreases, hence solubility decreases
