Consider an electrolytic cell at 298 k based on the following two half reactions hg2 2+ + 2e- æ 2 hg (l) 0.80 v fe3+ + e- æ fe 2+ 0.77 v under standard conditions. what will the potential of this cell be when the concentration of hg2 2+ has changed by 0.35 m? you can assume that the volumes of all solutions are exactly 1.0 l for this problem.
