__FOR 3/28/01, Wednesday CHAPTERS
1, 35, 2, 3__

__DUE: A list of the new vocabulary
words that you found in today's reading.__

__STUDY: P. 20:1-6, p.98: # 12,
13, 14, 15__

__Chapter 1: Read to see
what Analytical Chemistry encompasses. Read and think to see if you tell
your roommate the steps in an analysis. Your problem is to determine the
moisture content in a wagon load of Illinois corn. This is the total analytical
process. Study Figure 1-1, p.3. Does Figure 1-1 remind you of the Scientific
Method?__

__Chapters 35: relates to the laboratory. You should
read carefully about the apparatus that you are using. The lab notebook
hints in Section 35-J are important. Use this chapter as a supplement to
your laboratory directions. Consult these pages as you would a reference
book. Read it once or twice now, later when you need a specific section
come back to the specific reference.__

__Chapter 2: Read it and think about what you are
reading. Chapters 2 is introductory of statistics. Define both verbally
and algebraically: mean, median, average, precision, accuracy, standard
deviation, relative standard deviation, error, relative error. Does Figure
2-2 make sense?__

__Chapter 3: Distinguish between determinant and random
[indeterminant errors]. Often when students read about errors they get
depressed. Errors are important, but we all survive and get good results.
I want you to be aware of errors and to be careful, BUT we can enjoy chemistry
and CHM 210 inspite of the errors that we all make! Pages 18 and 19 are
important. Review the use of significant figures. What is the normal curve?
Do you want me to make your grades fit a normal curve? Think about the
rejection of "outliers" and use the Confidence limits and "Q Test" to determine
rejection.Carefully review the terms in this chapter. These terms will
be important as we treat data obtained in the laboratory. Especially note:
absolute error, accuracy, average deviation, confidence interval, constant
error, control chart, determinate error, normal distribution, intermediate
error, mean, median, precision, proportional error, Q-test, range, relative
error, significant figure, standard deviation, variance. A good exercise
is to write out the answers to questions 2-1,2-2,2-3,2-4,2-5,2-6 on page
20. Note on page 44 the highlighted gold note! Take this note to heart.__

__NOTE THE WORDS WHICH ARE NEW VOCABULARY WORDS FOR
YOU.__

__FOR 3/0, FRIDAY- CHAPTERS 2, 3, 4__

__DUE: Problem 1 to be distributed__

__STUDY:PAGE 20: 8, & Page 44: 5, 6, PAGE 68:
1, 2, 3, 4, 7, 13, 16, and those similar to previous ones__

__Review Chapters 2 and 3 and begin to read Chapter
4.__

__Chapter 4: 4-A gives you some statistical background,
note the marginal notes. Section 3-B is very important. These are the applications
that we will make of statistics. Study the terms: average deviation, confidence
interval, constant error, control chart, determinate error, normal distribution,
intermediate error, mean, median, precision, proportional error, Q-test,
range, relative error, significant figure, standard deviation, variance.
Can you clearly define each term. Does the term mean something to you?
Can you describe the process, or make the calculations needed? p.45 and
section 3B-2 is very important. I expect you to use the Q test in the laboratory.
We will be working on laboratory data to gain experience in using the Q
test and rejecting outliers. Section 3B-3 is also important. When data
is graphed, one needs to treat it statistically. The computer is a big
help in data treatment.__

__FOR 4/2, Monday, Chapter 4 and PROBLEMS TO DATE__

__DUE: those assigned.__

__STUDY: p.61: 4-16, 4-17, 4-19, and p.98: 5-1, 5-2,
5-4, 5-5, 5-7, 5-9. 5-21__

__Gravimetric analysis is an important tool in analysis.
Section 5A is important. Study Ex. 5-4. This is the stoichiometry in action.
Examples 5-5, 5-6, and 5-7 are nice one. On page 80 learn equation 5-2.
YES, MEMORIZE IT! GF means gravimetric factor. Section 5-B is important
to understanding what is happening in the beaker during a precipitation.
5B-5 is a neat technique. Note well. 5-C is a needed step. Read 5-D. Tables
5-3 and 5-4 show the breadth of gravimetric methods.__

__FOR 4/4, Wednesday, Chapter 5__

__DUE: To be assigned__

__Study 5-16, 5-20, 5-25 5-28__

__REVIEW THE PROBLEMS TO DATE and THE WORK THAT YOU
HAVE DONE IN LAB.__
