1.	Sodium sulphate in soluble in water but barium sulphate is sparingly soluble because
Answer» The hydration energy of `Na_(2)SO_(4)` is more than its LATTICE energy while the lattice energy of `BaSO_(4)` is more than its hydration energy The lattice energy has no role to play in solubility the lattice energy of `Na_(2)SO_(4)` is more tha its hydration energy None of these. Solution :`Na_(2)SO_(4)` is soluble in water because its hydration energy is MUCH more than its lattice energy. `BaSO_(4)` is INSOLUBLE in water because its lattice energy is much more than its hydration energy.
