Q.
Among the following, the compound that is readily soluble in water is
J & K CETJ & K CET 2011The s-Block Elements
Solution:
The solubility of alkaline earth metal sulphates decreases down the group because ionic size increases. $BeSO _{4}$ is readily soluble in water, because the greater hydration enthalpy of $Be ^{2+}$ ion overcomers the lattice enthalpy factor.
