How many of the following alkaline earth metal sulphates are readily soluble in water at room temper — s Block Elements Chemistry Question

💡 Solution & Explanation

Solubility of alkaline earth metal sulphates decreases down the group. $BeSO_4$ and $MgSO_4$ are readily soluble due to their very high hydration enthalpies overcoming lattice energy. $CaSO_4$ is sparingly soluble, while $SrSO_4$ and $BaSO_4$ are virtually insoluble.
