Question

Assertion (A): The Fountain experiment is used to demonstrate the high solubility of HCl gas. 

Reason (R): Red litmus solution turns blue in Fountain experiment.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Options

• (1)

• (2)

• (3)

• (4)

Answer 1

(3)

Explanation:

The fountain experiment demonstrates the high solubility of hydrogen chloride (HCl) gas in water. Therefore, the Assertion (A) is true.

HCl is acidic in nature and turns blue litmus red. It does not turn red litmus blue. Therefore, the Reason (R) is false.

Hence, A is true and R is false.
