Chem 165 Class 29 Chapter 19: Electrochemistry Objectives today: 1. Introduce the Nernst equation and the effects of concentration on cell potentials. 2. Discuss applications of electrochemistry: batteries, fuel cells, corrosion, and electrolysis/electroplating. Text: Chapter 19: Sections 4, 5, and 8; Next class: Course Review ARIS: Chapter 19-A: assignment due Tuesday (4/28) at 10:00 pm CDT ARIS: Chapter 19-B: assignment due Friday (5/1) at 6:00 pm CDT Suggested Problems (Class 29): 30, 34, 45, 46, 48, 56, 57 Final Exam: Wednesday, May 6, 7:00 – 9:00 pm, same room/seat assignments Review session: Sunday, May 3, 6:00 pm, 1002 Gilman Evaluations (For TA/recitation and for H. Stauffer/lecture): Due Friday (5/1) at 8:00 am Caption : A schematic depiction of the Hall process, in which aluminum oxide (the mineral corundum ) is reduced to pure aluminum via electrolysis using carbon anodes at a high temperature (>1000° C). The reaction 2 Al 2 O 3 4 Al( l ) + 3O 2 ( g ), in which aluminum is reduced by oxide ions, is not a spontaneous redox reaction; electrolytic work must be done to drive this reaction. Since the purified liquid Al metal sinks to the bottom of the reaction vessel, it can be drained from the vessel during the procedure.
