Problem: 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 forF2 + 2 e‒ → 2 F‒A. +5.92 VB. -5.92 VC. +2.87 VD. +3.07 VE. +0.18 VF. -0.18 V

FREE Expert Solution

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


Calculate E°cell:
