Hydration energy of the given ions follows the order.

The ease of adsorption of the hydrated alkali metal ions on the ion-exchange resins follows the order -

Solubility depends on the lattice energy of the solid and the hydration energy of the ions. Some lattice values for Group - II compounds are much lighter than the values for Group - I compounds, because of the effect of the increased charge on the ions in the Boron - Lande equation. Taking any one particular negative ion the lattice energy decreases as the size of the metal increases. The hydration energy also decreases as the metal ions become larger. For a substance to dissolve, the hydration energy must exceed thelattice energy The correct order of hydration energies is

The solubility of most salts depends on the lattice energy of the solid and the hydration energy of the ions. On descending the group, the hydration energy decreases more rapidly than the lattice energy, hence the compound become less soluble as the metals gets larger. however, with the fluorides and hydroxides and the lattice energy decreases more rapidly than the hydration energy and so their solubility increases on descending the group.
