For the a voltaic cell with the overall reaction:
Zn(s) + Cu 2+(aq) → Zn 2+(aq) + Cu(s) E o cell = 1.10 V
Given that the standard reduction potential of Zn 2+ to Zn(s) is – 0.76 V, calculate the standard reduction potential for:
Cu 2+(aq) + 2e − → Cu(s)
A. 0.76 V
B. −0.76 V
C. 1.86 V
D. −1.86 V
E. 0.34 V
