Ch. 17 Essential Questions:
• How can you predict and write net ionic reactions for the following reaction types:
oxidation/reduction?
• How can you explain galvanic and electrolytic cells?
• How can you relate free energy change to equilibrium constants and electrode
potentials?
AP Chemistry Review Assignment - DUE _________________ (the day before the Ch. 17 test)
Your task is to:
1) Make a review sheet (one page front and back maximum) for the entire class
• It must be typed and organized in a logical manner
2) Present the main ideas to the class using your sheet as a guide ~5 min.
Be sure to include:
a. All the BIG concepts for your chapter. If you're not sure if something is "BIG" ask me.
b. Any important/useful diagrams.
• I can have figures from your book photocopied for you if you write me a list of the page #'s you need
copied (and if you want me to shrink/enlarge the image by a certain %) by Thurs 2-28
c. Some worked out example problems (if important to your chapter). (Don’t include ex. problems without
answers.)
d. A list of common misconceptions/mistakes people may make.
POINTS WILL BE DEDUCTED FOR SLOPPY/INCOMPLETE (not thorough) WORK.
** Please submit your review sheet single-sided. Thanks!

Ch. 17 Unit Objectives
Problem Set 17.1 – Introduction to Electrochemistry – terms, voltaic cells, cell potential
1) Students will have be able to explain the terms: oxidation, reduction, oxidizing agent, reducing agent.
2) Student will be able to balance redox reactions by the half-reaction method.
3) Given two metals (and metal soltions) tudent will be able to draw a voltaic cell and label the following: cathode, anode,
direction of electron flow, direction of ion flow in solution and in salt bridge.
4) Students will be able to draw the shorthand notation for a voltaic cell.
5) Students will be able to calculate the cell potential for a voltaic cell and predict what reactions are spontaneous.
6) Students will be able to organize a list of substances into columns showing strength as oxidizing and reducing agents
(knowing some qualify in only one category, while others qualify in both).
Problem Set 17.2 – Cell potential, electrical work, and free energy; LeChatelier & Nernst
1) Students will be able to calculate the work possible given a volaic cell (by first calculating the cell potential).
2) Students will know how charge relates to number of electrons (using Faraday’s constant).
3) Students will be able to predict qualitatively what happens to cell potential when concentrations of ions are changed
(LeChatelier).
4) Students will be able to predict quantitatively what happens to cell potential when concentrations of ions are changed
(Nernst).
Problem Set 17.3 – Electrolytic cells, predicting electrolytic reactions; batteries
1) Students will be able to describe the difference between a voltaic and an electrolytic cell.
2) Students will be able to calculate how much metal can be plated when a specific current flows for a specified amount of
time.
3) Students will be able to predict what reactions happen at the anode and cathod of an electrolytic cell.
4) Students will have a basic understanding of how a variety of batteries work.
