The solubility of sulphates in water down the Be group is Be>Mg>Ca>Sr>Ba This is due to

  1. A

    High heat of solvation for smaller ions like Be2+

  2. B

    Increasing molecular weight

  3. C

    Decreasing lattice energy

  4. D

    Increase in melting points

    Solution:

    The hydration energy decreases from Be+2 to Ba+2 This causes the decrease in the solubilities of the sulphates in this order. In other words, the solubilities decreases with increase in the ionic size.
