Vedclass · Answer

(A) The solubility of alkaline earth metal sulfates decreases down the group. This is primarily because the hydration enthalpy of the metal ions decreases significantly from $Be^{2+}$ to $Ba^{2+}$ as the ionic size increases. Since the sulfate ion is large,the lattice energy does not decrease as rapidly as the hydration enthalpy,leading to a decrease in overall solubility.

The solubility of sulfates in water decreases down the group for $Be$ to $Ba$. The correct order is $BeSO_4 > MgSO_4 > CaSO_4 > SrSO_4 > BaSO_4$. The reason for this is:
