Question

Assertion: Copper can displace zinc from the solution of zinc sulphate.

Reason: Copper is placed below zinc in the electrochemical series.

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 Assertion is INCORRECT but Reason is CORRECT.

Explanation:

Copper cannot displace zinc from the solution of zinc sulphate because copper is below zinc in the electrochemical series. The displacement reaction occurs only when a metal is above another metal in the series, as it has a higher reducing power. Hence, the assertion is incorrect, but the reason (that copper is below zinc in the electrochemical series) is correct.
