The solubilities of carbonates decrease down the magnesium group due to a decrease in

Question

The solubilities of carbonates decrease down the magnesium group due to a decrease in (A) lattice energies of solids (B) hydration energies of cations (C) inter-ionic attraction (D) entropy of solution formation

Tardigrade Admin · Accepted Answer

Solubilities of carbonates decreases down the group because lattice energy decrease is almost constant while decrease in hydration energy downs sharply, finally difference of hydration energy and lattice energy decrease thus solubility decreases.
