Solubility of alkaline earth metal sulphates decreases down the group 2 becauseA. they become more ionicB. lattica energy of sulphates does not vary siginifacantlyC. hydration energy decreases rapidly from `Be^(2+)` to `Ba^(2+)`D. latica energy plays more predominant role than hydration energy |
|
Answer» Correct Answer - c Duet to very large size of sulphate ions, the magnitude of lattice energy of alkaline earth metal sulphates remains almost constant. Thus, their solubility is only govermed by hydration energy which decreases from `Be^(2+)` to `Ba^(2+)` |
