Question

The right order of the solubility of sulphates of alkaline earth metals in water is (A) Be > Ca > Mg > Ba > Sr (B) Mg > Be > Ba > Ca > Sr (C) Be > Mg > Ca > Sr > Ba (D) Mg > Ca > Ba > Be > Sr

Tardigrade Admin · Accepted Answer

Be > Mg > Ca > Sr > Ba. The size of the SO42- ion is very big (approx. 3 overset texto mathop textA ). Therefore, as the size of the cation increases, their hydration energies decrease more rapidly than their lattice energies. Consequently the solubilities of sulphates decrease down the group.

Mg > Be > Ba > Ca > Sr

Be > Mg > Ca > Sr > Ba

Mg > Ca > Ba > Be > Sr

Be > Mg > Ca > Sr > Ba. The size of the $S O_{4}^{2 -}$ ion is very big (approx. 3 $A o$ ). Therefore, as the size of the cation increases, their hydration energies decrease more rapidly than their lattice energies. Consequently the solubilities of sulphates decrease down the group.
