Design a voltaic cell from the following half-reactions:
Cr2O7(aq) + 14 H+(aq) + 6 e − → 2 Cr3+(aq) + 7 H2O(l) E° = 1.33
O2(g) + 4 H+(aq) + 4 e − → 2 H2O(l) E° = 1.23
In the overall reaction, how many H + ions would be shown and which side would they be on?
A. 18 on the left
B. 16 on the left
C. 10 on the left
D. 10 on the right
E. 12 on the right
