Statement 1: Solubilities of alkali metal fluorides and carbonates increase down the group.Statement 2: Hydration energies of alkali metal halides decrease down the group with increase in size of cations.

Statement 1 : The reason for this is that their lattice energy and hydration energy both decreases down the group, change in lattice energy is more than the hydration energy.Statement 2 : Hydration energy ∝ 1size of cation.
