14.23A

Postby Elizabeth Ignacio 1C » Mon Feb 19, 2018 11:13 am

One of half reactions needed to calculate the overall cell potential in 14.23A is 2Hg -> Hg22+ + 2e- and the cell potential for the reverse reaction in the textbook is listed as +0.79, which the solutions manual uses in the calculations for Eocell. I'm confused why they didn't flip the cell potential to get -0.79 if the positive version was the reverse of the reaction that was actually happening.

I'm not really sure why but my TA said that we don't flip potentials because the redox couple is the same.
