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
(a) Correct For greater solubility, hydration energy must be greater than lattice energy.
(b) Correct Greater lattice energy dicourage dissolution of a salt.
(c) Incorrect When a salt dissolve, energy is required to break the lattice, which comes from hydration process.
(d) Incorrect Explained in (A).
