Q. Statement 1: $BeSO_{4}$ and $MgSO_{4}$ are soluble in water
Statement 2: $BaSO_{4}$ is water insoluble because lattice energy of $BaSO_{4}$ is higher than its hydration energy

The s-Block Elements

Solution:

$BeSO_{4}$ and $MgSO_{4}$ are readily soluble in water; the solubility decreases from $CaSO_{4}$ to $BaSO_{4}$ The greater hydration enthalpies of $Be^{2+}$ and $Mg^{2+}$ ions overcome the lattice enthalpy factor and therefore their sulphates are soluble in water
