Given the following pair of half-reactions, fill in the line notation for a standard cell using these two half-reactions. Since it is a standard cell, all concentrations will be 1 M, so do not enter concentrations. You have solid platinum (Pt) electrodes to use, where necessary. Do not include the physical state of the components, i.e., solid platinum would just be Pt. For subscript and superscripts use the model: Ag+ would be Ag^+ and SO42- would be entered as SO4^2-, with the "^" character indicating a superscript. Leave a space between components.
I3- (aq) + 2e- → 3 I- (aq) ξo = 0.55
Tl3+ (aq) + 2e- → Tl+ (aq) ξo = 1.24

7. Given the standard reduction potential for the following two
half-cell reactions (in the presence of 1.00 M HCl):
Fe3+ + e <==> Fe2+, E0 = + 0.68 V
AsO4 - + 2H+ + 2e <==> AsO3 - + H2O, Eo = +0.559 V.
Please calculate the system potential at the equivalence point
when Fe3+ was used to titrate AsO3 - in the presence of 1.00 M
HCl.
Answer: 0.60 V
