Question

$N{a}_{2}S{O}_4$ is soluble in water while $BaS{o}_4$ is insoluble. Which of the reason is correct about the above statement

• A. Lattice energy of BaSO₄ exceeds its hydration energy
• B. Hydration energy of BaSO₄ exceeds its hydration energy
• C. The solubility in H₂O of a compound depends only on its hydration energy
• D. The solubility in H₂O of a compound depends only on its lattice energy

Answer 1

The correct option is A

Lattice energy of BaSO₄ exceeds its hydration energy

If L.E > H.E, the compound would be insoluble in water
