Question

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

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

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.
