Question

Given Cu²⁺(aq) + 2e^- → Cu(s) E° = +0.34 V Al³⁺(aq) + 3e^- → Al(s) E° = -1.66 V Na⁺(aq) + e^- → Na(s) E° = -2.71 V Which of the following reactions will occur?

Quizplus · Accepted Answer

The reaction C is spontaneous because the reduction potential of Cu²⁺ is higher than that of Na⁺, making the overall cell potential positive.

Given Cu2+(aq) + 2e- → Cu(s) E° = +0

Given Cu²⁺(aq) + 2e^- → Cu(s) E° = +0
