Predict the potential during a potentiometric redox titration of Fe2+ (analyte) with Ce4+ (titrant) at 25 °C when the titration is 33% of the way to the equivalence point when a silver-silver chloride reference electrode (0.197 V) is connected to the anode and a platinum wire connected at the cathode is placed in the titration beaker. Ce4+ (aq) + 1e > Ce3+(aq) E° = 1.610 V Fe3+ (aq) + 1e → > Fe2+(aq) E° = 0.771 V 0.592

Question
Predict the potential during a potentiometric redox
titration of Fe2+ (analyte) with Ce4+ (titrant) at 25 °C when
the titration is 33% of the way to the equivalence point
when a silver-silver chloride reference electrode (0.197 V)
is connected to the anode and a platinum wire connected
at the cathode is placed in the titration beaker.
Ce4+ (aq) + 1e
> Ce3+(aq)
E° = 1.610 V
Fe3+ (aq) + 1e
→
> Fe2+(aq)
E° = 0.771 V
0.592
