Question

Assertion (A): HCI can be tested by AgNO₃ solution.

Reason (R): White precipitate of AgCl is formed when AgNO₃ is added to HCl.

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

(1)

Explanation:

Hydrochloric acid can be tested using silver nitrate solution. Therefore, the Assertion (A) is true.

When silver nitrate is added to HCl, a white precipitate of silver chloride (AgCl) is formed. Therefore, the Reason (R) is also true.

\[\ce{HCl + AgNO3−>AgCl + HNO3}\]

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