6.57

Postby Michelle Song 1G » Tue Mar 12, 2019 6:12 pm

Can someone please explain how to find the cathode and why which equation is the cathode/anode?

The solutions manual says that the reduction of F2 is the cathode even though its reduction potential is lower than that of the supposed anode.

Usually the cathode should be whatever has a higher reduction potential, because reducing this species would be more favorable. Many of the solutions in this section are unclear in their reasoning. Having the species with the lower reduction potential be the species that is reduced would make the overall cell potential negative, which does not make physical sense.

Does this mean that the solution is wrong?
