Were being asked to determine the potential of F2 + 2 e‒ → 2 F‒ when the reduction of Li+ to Li established as E◦ = 0 V.
Recall the Standard Hydrogen Electrode (S. H. E.): 2 H+(aq) + 2 e- → H2(g)
▪ Cell potential of S. H. E.: E°cell = 0 V
From the standard reduction potential table:
Li+ + e- → Li E° = -3.0401 V
F2 + 2 e‒ → 2 F‒ E° = +2.866 V
You decide that you have had enough using the standard hydrogen electrode as the definition of zero potential. You run a campaign with the International Union of Pure and Applied Chemists to have the reduction of Li+ to Li established as E◦ = 0 V. In this new proposed standard, what would the potential be for
F2 + 2 e‒ → 2 F‒
A. +5.92 V
B. -5.92 V
C. +2.87 V
D. +3.07 V
E. +0.18 V
F. -0.18 V
