Vedclass · Answer

(A) The solubility of an ionic compound in water depends on the balance between its lattice energy and hydration energy. For a compound to be soluble,the hydration energy must be greater than the lattice energy. In the case of $Na_2SO_4$,the hydration energy of the ions is sufficient to overcome 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.
