Vedclass · Accepted Answer

The hydration energy of $Na_2SO_4$ is greater than its lattice energy,whereas the lattice energy of $BaSO_4$ is greater than its hydration energy.

Vedclass · Answer

(A) For a compound to be soluble in water,its hydration energy must be greater than its lattice energy.In the case of $Na_2SO_4$,the hydration energy is higher than the lattice energy,making it soluble.In the case of $BaSO_4$,the lattice energy is significantly higher than the hydration energy due to the high charge density and size factors,making it sparingly soluble.
