Question

Assertion :$C{u}^{2+}$ ions get reduced more easily than $H^{+}$ ions. Reason: Standard electrode potential of copper is $0.34$V.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

$Cu$ is placed above hydrogen in electrochemical series. So, $Cu$ is having more reduction potential than Hydrogen. We know that more the reduction potential more easily the element gets reduced and acts as a good oxidising agent.

Hence, $C{u}^{2+}$ is reduced more easily than $H^{+}$.

$C{u}^{2+}$ is reduced more easily than $H^{+}$ because of Copper having higher electrode potential than Hydrogen and hence reason is the correct explanation for Assertion.
