Solubility of an ionic compound in water is mainly dependent on: a.Lattice enthalpy , b. Hydration enthalphy Both these factors oppose each other and the resultant of these determines the solubility of an ionic compound in water. If lattce enthalpy has greater value, the compound is less soluble. In case hydration enthalpy has greater value, the compound is highly soluble in water.
