Question

Assertion (A): Hydrochloric acid is prepared by dissolving HCl gas in water.

Reason (R): HCl gas dissolves in water and less pressure is created to avoid back suction.

Options

• If both A and R are true, and R is the correct explanation of A.

• If both A and R are true, but R is not the correct explanation of A.

• If A is true, but R is false.

• If both A and R are false.

If both A and R are true, but R is not the correct explanation of A.

Explanation:

The assertion is true because hydrochloric acid is made by dissolving hydrogen chloride gas in water. The reason is also factually true because the gas dissolves so rapidly that it creates a partial vacuum (low pressure) inside the tube, pulling water upward. However, this low pressure actually causes
