The right order of the solubility of sulphates of alkaline earth metals in water is
Open in App
Solution
The correct option is C Be > Mg > Ca > Sr > Ba
Be > Mg > Ca > Sr > Ba
On moving down the group lattice energy remains almost constant as the sulphate is so big that small
increase in the size of the cations fromBe toBa does not make any difference. However the hydration
energy decreases from Be2+ to Ba+2 . This causes decrease in the solubility of the sulphates as the ionic size increases.
