In class this week, we discussed the titration of Sn²+ (aq) with Fe³+ (aq) react according to the following chemical equation: 2Fe³+ (aq) + Sn²+ (aq) ⇒ 2Fe²+ (aq) + Sn4+ (aq) The relevant half reactions (taken from Appendix H) are copied below: Fe³+ + e* = Fe²+ Eº = 0.732 V Sn4+ + 2e Sn²+ Eº = 0.139 V In one experiment, 25 mL of 0.050 M Sn²+ is titrated with 0.10 M Fe³+; the titration is monitored using a Pt working electrode (red, positive lead) and a Ag/AgCl reference electrode (black, negative lead). What is the potential (in V) you would expect to measure after 30.0 mL of the titrant has been added? To make sure your answer falls within the acceptable range of numerical accuracy, input it to at least three significant digits.
