Question

What is the standard electrode potential for the reduction half-reaction \( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} \)?

• A. +0.34 V
• B. -0.34 V
• C. +0.72 V
• D. -0.72 V

Hint:

The standard electrode potential represents the tendency of a species to gain electrons and be reduced. The more positive the potential, the greater the tendency to be reduced.

Answer 1

The Correct Option is A

The standard electrode potential for the reduction half-reaction \( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} \) is \( +0.34 \, \text{V} \).
