Q. Solubilities of carbonates decreases down the magnesium group due to decreases in

Q. Lattice energy and hydration energy are two important properties of ionic solids on which their melting point, boiling point and solubility depend. Lattice energy increases as the charge on the ion increases and the size decreases. Hydration energy increases as the size of the ion decreases and charges on it increases.
The solubilities of carbonates, sulphates and phosphates of alkaline earth metals are much less than those of the corresponding alkali metals. This is because:

Q. The solubility of ionic solids decreases when hydration energy of ions increases.

B e S O_{4}

is soluble in water while

B a S O_{4}

is not.
Reason : Hydration energy decreases down the group from Be to Ba and lattice energy remains almost constant.

Q. The solubilities of carbonates decrease down the Mg group due to a decrease in
