Question

Statement 1: The solubility of sodium sulphate first increases then decreases.

Statement 2: This represents anomalous solubility of sodium sulphate.

• A. Only statement 1 is correct.
• B. Only statement 2 is correct.
• C. Statement 1 and statement 2 both are correct.
• D. Statement 1 and statement 2 both are wrong.

Answer 1

The correct option is C

Statement 1 and statement 2 both are correct.

Some salts like sodium sulphate show anomalous solubility, first their solubility increases with temperature then decreases i.e. it becomes independent of the temperature.
