    Solubilities of carbonates decrease down the magnesium group due to decease in:

    A) Entropy of solution formation

    B) Lattice energies of solids

    C) Hydration energy of cations

    D) Inter-ionic attraction

    Correct Answer: C

    Solution :

    [c] Hydration energy of cations Solubilities of carbonates decreases down the magnesium group due to the reason that their lattice energies decrease more rapidly than their hydration energies on moving down the group.
