COURSE OBJECTIVES
The goal of this course is to introduce students to the broad, important area of
quantitative chemical analysis as preparation for upper level coursework and graduate
study, as well as for careers in industry, medicine, and government.
In the laboratory, basic techniques are stressed first. These include using the balances,
care and use of volumetric glassware, and data analysis using a spreadsheet program.
From there, gravimetric analyses (analysis by weight) and volumetric analysis
(titrations) are introduced. The application of chemical equilibrium in analysis is
illustrated by neutralization, complexation, and redox titrations.
The coursework outside of the laboratory will cover methods of statistical analysis. In
addition, the theory behind the laboratory techniques mentioned above will be
explained, as well as how reliable they are and what limitations might be encountered.
Upon completion of this course, the student should possess the ability to carry out the
following steps of an analytical experiment:
1. Evaluation of a chemical problem and the selection of appropriate analytical
techniques to address it, keeping in mind the chemistry behind each method and the
limitations associated with it.
2. Carrying out the analytical methods in the laboratory, keeping in mind safety, the
required precision, and the maximum use of laboratory time.
3. Analysis of the raw data using spreadsheet technology, arriving at not only a
numerical result, but also an estimate of the precision and the statistical confidence
associated with any answers to questions associated with the result.
4. Effective communication of the process behind solving the problem, including the
theory behind the technique and any problems that were encountered.
V.
COURSE COMPETENCIES
The student will apply and refine his/her previous knowledge and develop the following
manual skills.
a. Quantitative transfer of a solid reagent, carrying out dilutions, drying or washing
volumetric glassware with the solution being measured when necessary.
b. Acid-base titration with strong reagents, aiming for a precision of two parts per
thousand.
c. Acid-base titration of a weak acid with a strong base, aiming at the same precision.
d. Acid-base titration of a weak diprotic acid or base, with the possible use of backtitration
e. Preparation and calculation of buffers.
f. Determination of a sulfate unknown by means of gravimetry.
g. Determination of an iron sample by means of a redox titration and/or colorimetry.
The student is expected to understand and show by means of word problems and tests
that (s)he understands and can apply the theory behind
a. The necessity to dry glassware or wash volumetric equipment with the solution
being measured, including understanding when these steps are not needed.
b. Acid-base titration including pH, titration curves, endpoint versus equivalence
point, selection of an indicator, weak acid or base, equivalence point of a salt,
hydrolysis of a salt, indicator error.
c. How balances work, as well as what limits their precision and accuracy.
d. Calibration of volumetric instrumentation.
e. Precipitation, Ksp, problem of co-precipitation, peptization, digestion of crystals to
obtain larger sizes, filtering by means of filter paper or sintered glass funnels.
f. Electron-transfer reactions that occur during a redox titration procedure.
g. Complexation equilibria that occur during EDTA metal analysis, including pH
dependence and desirable indicator characteristics.
h. Sampling techniques and statistical analysis.
i. What the requirements are for a primary standard.
VI.
EVALUATION CRITERIA
The progress of each student will be evaluated by means of three one-hour examinations
given during the semester, laboratory reports, homework, quizzes, and a final
examination.

COURSE REQUIREMENTS
A. Hour exams are in the short-essay format. However, you may have multiple
choice questions as well. Questions may consist of either a numerical problem
to work out or a concept to explain in a few sentences. To receive full credit
for numerical problems, make sure your thought process is written out clearly.
B. Laboratory reports. The laboratory is an important component of the course.
Laboratory procedures are on chapter 37 in your textbook. In the new version
of your book, the experiments are in CD-ROM; so you have to print them out
from there. Each laboratory experiment has three components.
a. Pre-lab: Read the procedure beforehand. Write it out in your own
words, and bring that procedure to lab, not your textbook. Write out
the procedure as step-by-step instructions and make a list of equipment
and chemicals at the top, with the hazards associated with each of the
chemicals.
b. In lab: Use your laboratory notebook to record what you have done,
not what you plan to do. Record raw data directly into the notebook as
you observe them; do not write weighings or buret readings on separate
pieces of paper to be transcribed later into the notebook.
c. Laboratory report: This is to have a title, author(s), abstract,
introduction, experimental, results and discussion, and reference(s).
Further details will be given.
You will be trained in the use of Microsoft Excel and will be expected to use it
for calculations.
IX.
TEACHING STRATEGIES
A variety of formats will be used in this class. Typically, the class will begin with
answering your questions about the homework or a ten-minute quiz, then new material
in a lecture format and then in-class exercises, with discussion in an interactive format.
