  • Solubility of an ionic compound in water is mainly dependent on A) Lattice enthalpy " " B) Hydration enathalpy Both these factors oppose each other and the resultant of these determines thhe solubility of an ionic compound in water. If lattice enthalpy has greater value, the compound has greater value, the compound is less soluble. In case hydration enthaply has greater value, the compound is highly soluble is water BeF_(2) is soluble in water while fluorides of other alkalie earth metals are isoluble because of

    Beryllium differs from other alkaline earth metals because of

    BeO and Be(OH)_(2) are amphoteric while the oxides and hydroxides of other alkaline earth metals are basic. The solubility of hydroxides increases as we move down the group from Be to Ba but the solubility of sulphates and carbonates decreases in that order the thermal stability of carbonates and sulphates of alkaline earth metals increases from Be to Ba as we move from top to bottom in the group. The solubility in water of sulphates down the Be group is Be gt Mg gt Ca gt Sr gt Ba this is due to
