  • question_answer
    The order solubility in water of alkaline earth metal sulphates down the group is \[Be>Mg>Ca>Sr>Ba\]. This is due to  increases in

    A) ionization energy            

    B) melting point

    C) coordination number      

    D) All of these

    Correct Answer: C

    Solution :

    [c] In crystalline sulphates, the coordination number of the ions increases from \[Be\] to \[Ba\] and so also the lattice energy hence solubility in \[{{H}_{2}}O\] decreases.
