A metal M readily forms water soluble sulphate, and water insoluble hydroxide M(OH)_(2) . Its oxide MO is amphoteric, hard and having high melting point. The alkaline earth metal M must be :

The solubility of a crystalline compound in water is influenced by two factors. These are lattice enthalpy and hydration enthalpy. Lattice enthalpy is needed to separate the ions from the crystal lattice. At the same time hydration enthalpy is released when the ion are dissolved in water. The resultant of these two opposing tendencies guides the solubility of the compound in water. If lattice enthalpy has a greater magnitude, the compound has low solubility. In case hydration enthalpy is more, then the compound is highly soluble in water. A metal M readily forms a water soluble sulphate MSO_(4) water insoluble hydroxide M(OH)_(2) and oxide MO which becomes inert upon heating. The hydroxide is soluble in NaOH. The metal M is
