A voltaic cell that uses the reaction
Tl3+(aq) + 2Cr2+(aq) → Tl+(aq) + 2Cr3+(aq)
has a measured standard cell potential of + 1.19 V.
(a) Write the two half-cell reactions.
(b) By using data from Appendix E, determine E°red for the reduction of Tl3+(aq) toTl+(aq).
(c) Sketch the voltaic cell, label the anode and cathode, and indicate the direction of electron flow.
