The halides of all other alkaline earth … The halides are soluble in water and their solubility decreases in the order: MgX 2 > CaX 2 > SrX 2 > BaX 2 BeF 2 is very soluble in water due to the high solvation energy of Be 2+ in forming but the fluorides of other alkaline earth metals have high melting point and they are insoluble in water. Increasing order of Ionization Energy: Li > Na > K > Rb > Cs . When alkali metal dissolves in liquid ammonia, the solution can acquire different colours. 2) The solubility of most of the alkali metal halides except those of fluoride decreases on descending the group since the decrease in hydration enthalpy is more than the corresponding decrease in the lattice enthalpy. .
