What is on the exam?  As stated in the syllabus, lectures and handouts, problem sets (practice and hand-in), and laboratory work define the main focus of this course. No textbook follows this course exactly.  When I suggest that you read a chapter of the text, there is often material therein that is not a focus of this course.  Conversely, I sometimes cover material in lecture that is not included in the text.  If you have memorized information as indicated on handouts, and can do and understand the problems and lab reports, you will be prepared for the exam.  The textbook is a good source of supplementary problems, but again, choose problems that relate to the topics central to the course.  I will not answer questions like "Are we responsible for,,,?"  It is part of your job as a college student to decide what you need to know. The study guides are meant to help you with this.

Exam 3 (Thursday, December 3, 2009)

Study Guide for Exam 3

Exam 3 data sheet: tables of K_a and K_sp that will be distributed.

Sample Exam 3: exam given in 2008
I urge you to use this as a practice exam.  Don't look at it until you have finished practice problem set 9 and reviewed the material. (In hand-in problem set 9, questions 1 and 3 are relevant to exam 3, while question 2, on redox half-reactions, is not.)  When you are ready to try the exam, have 90 minutes available, avoid interruptions, and time yourself.  Look at the answers only after you have worked hard on each question.

Answers to sample exam 3. Check your answers, including units and significant figures.  Read all comments (in italics) carefully.   Come ask questions if anything is unclear!
