SUMMARY
The balanced equation for the redox reaction between Sn2+ and Tl3+ is Sn2+ + Tl3+ → Sn4+ + Tl+. This reaction occurs during the titration of 50 mL of 0.10M Sn2+ with 0.10M Tl3+, where thallium is reduced to its +1 oxidation state and tin(II) is oxidized to tin(IV). The half-cell potential after the addition of 5.00 mL of Tl3+ is calculated to be E1/2 = 0.156 V, based on the formula E1/2 = 0.139 - (0.05196/2) log(1/4.5).
