Sodium sulphate is soluble in water,wher...

Sodium sulphate is soluble in water,whereas barium sulphate is sparingly soluble because

A

The hydration energy of sodium sulphate is more than its lattice energy

B

The lattice energy of barium sulphate is more than its hydration energy

C

The lattice energy has no role to play in solubility

D

The hydration energy of sodium sulphate is less than its lattice energy

Text Solution

Verified by Experts

The correct Answer is:
A, B
`BaSO_(4)` is sparingly soluble in water because its hydration energy is lesser than the lattice energy and thus ions are not separated from each other. On the contrary in `Na_(2)SO_(4)`, the hydration energy is more than its lattice energy. Thus ions are separated from each other and pass in solution state.
