Solubility in water is related to the ionic nature and size. Answer: Alkali metals are highly reactive in nature. The best known of these compounds is sodium chloride, table salt. Alkali metal halides are soluble in water due to their high ionic character and low lattice energy. However, these hydroxides are less basic than the corresponding alkali metal hydroxides because of higher ionization energies, smaller ionic sizes and greater lattice energies.
