Test #1 Study Guide

Topics

For this test, you will be responsible for the following subjects:

1. Introduction to analytical chemistry
2. Gravimetry analysis.
3. Inorganic aqueous chemistry
4. Titrimetry (concepts and methods)

The relevant Course Topics sections list the topics that are usually covered in lecture. However, time constaints are sometimes such that we must skip a few topics; these missed topics, which have open circles as bullets, will not be on the test. Note: you must use at least a 4.0-level browser (Netscape Navigator or Internet Explorer) to see the open circles.

Study Material

The following material will be useful in studying for the test (most of the following are PDF documents):

• Harris chapters 0, 1, 6, 7, 10 - 13, 16, 27. You ought to read these chapters in their entirely at least once (ideally, you have already done so). However, focus attention on topics discussed during lecture. You will not be tested on material that was not given in the lecture (i.e., the topics listed in the relevant sections of the Course Topics). You might want to use the textbook to help expand upon your own lectures notes.
• lab: Gravimetric determination of sulfate
• lab: Titrimetric determination of chloride
• lab: Redox titrations with iodine. This is a round-robin experiment, so most of you have not done it yet. However, the experiment is an application of methods discussed in class on Tuesday. I would strongly recommend that you read and understand this experiment.
• lecture supplemental notes: Titrimetric Analysis: Methods. You should definitely know the material on acid-base, precipitation and redox titrations. Complexometric titrations were not covered in class at the same level of detail as they are discussed in these notes. However, you should still understand what EDTA titrations are, what they are used for, and how the EDTA titrant is prepared and standardized.
• Homework #1 Key. Use this key to understand what I would consider "ideal" answers to test questions like those on your homework.

Suggested Problems

I have included these as a study aid. Once you've mastered the material, you should be able to do the following problems from the Harris textbook. These problems are not meant to provide comprehensive coverage of the material on the test; I would not spend an inordinate amount of time doing them. Note that the capital letters refer to the Exercises at the end of the chapters, while the numbers refer to the Problems.

Chapter 1: 12, 13, 16-18, 21
Chapter 6: H; 3, 27, 32-34, 37, 39, 45, 47-54
Chapter 7: A-C; 1-4, 8-10, 14, 18, 31, 33, 35
Chapter 10: 5, 16
Chapter 11: 21-23
Chapter 12: 4, 5, 12, 13, 16, 19, 36, 37, 46, 48, 50, 51, 56
Chapter 13: A-B, 1, 22, 27, 30, 31, 34-35
Chapter 16: 8, 10, 16-18, 20, 27
Chapter 27: 2-7, 10, 16, 23.

The bolded problems are calculations. Approximately 25% of the points on the test will be for calculations. You will be expected to know how to do the following types of calculations:

• convert between different concentration units
• calculate analyte concentration using data from gravimetric experiments
• calculate analyte concentration using data from titrimetric experiments

You will not have to do statistics-type calculations. In other words, you won't have to calculate confidence intervals, or pool data, or the like.
