Sample Problem 21.4
Writing spontaneous redox reactions and ranking oxidizing and reducing agents by strength
PLAN:
(b) Rank the relative strengths of the oxidizing and reducing agents:
Put the equations together in varying combinations so as to produce (+) Eocell for the combination. Since the reactions are written as reductions, remember that as you reverse one reaction for an oxidation, reverse the sign of Eo. Balance the number of
In ranking the strengths, compare the combinations in terms of Eocell.
