Question

Assertion: When a solution of sodium argentocyanide is treated with scrap zinc, silver gets precipitated.

Reason: Zinc is more electropositive than silver.

विकल्प

• If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

• If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.

• If Assertion is CORRECT but Reason is INCORRECT.

• If Assertion is INCORRECT but Reason is CORRECT.

Answer 1

If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

Explanation:

The assertion is correct because when sodium argentocyanide solution is treated with scrap zinc, silver is displaced and gets precipitated. The reason is also correct because zinc is more electropositive (more reactive) than silver, so it displaces silver from its complex. Hence, the reason correctly explains the assertion.
