Amongst fluorides of alkali metals, the lowest solubility of LiF in water is due to (a) ionic nature of lithium fluoride. The solubility of alkaline earth carbonate and sulfates decrease down the group because the hydration energies decrease. Soluble inorganic fluorides can react slowly with water to form hydrofluoric acid. The halides are soluble in water and their solubility decreases in the order: MgX 2 > CaX 2 > SrX 2 > BaX 2. Hydroxides of the lighter alkaline earth metals are insoluble in water, but their solubility increases as the atomic number of the metal increases.
