Quantitative Chemical Analysis, 8th Edition, by Daniel C. Harris
CHEM 321: Quantitative Analysis: “Leverette’s Lecture Notebook”, Fall 2014, Version IV
Scientific calculator (capable of log, scientific notation, square root, nth root, and exponents)
*Although the text for the course is Quantitative Chemical Analysis, the lectures will consist of
information pulled from a variety of sources. The assigned homework problems will come from
the text. My plan for us is to work straight through the book covering the material in the order
Harris suggests. This should allow you to follow along with the text as I lecture. This text is an
easy read so I expect students to read the chapters that we cover as we are going through the
material. Success in the course is achieved by taking excellent notes, reading the
text/assigned readings to reinforce what we do in class, reviewing the material each day,
and practicing the problems.
Course Objectives: Quantitative analysis is an introduction course into the field of analytical
chemistry. The goals of this course, as stated in the Programs Bulletin, are to provide practice of
volumetric and gravimetric analysis with exposure to spectroscopic, chromatographic, and
electrochemical methods. Beyond these basics, my personal goal is to provide you with the
answer to the question, “What is analytical chemistry?” I hope that you will see analytical
chemistry as the “measurement science”, and how analytical chemistry impacts all forms of
research, from medical applications to industrial product development. Modern day applications
of this “measurement science” bridge the scientific fields of biochemistry, physical chemistry,
biology, physics, and materials science. David Harvey, author of Modern Analytical Chemistry
stated that “the craft of analytical chemistry is not in performing a routine analysis on a routine
sample, but in improving established methods and techniques, extending methods to new types of
samples, and developing new methods for measuring chemical phenomena.” In essence,
analytical chemists are problem solvers. In this course, we will cover more traditional wetchemistry techniques that represent the earliest beginnings of analytical chemistry as well as
modern techniques utilizing state-of-the-art instrumentation. After a short review of some key
concepts learned in freshman chemistry, we will learn how to evaluate chemical data utilizing
data analysis and statistics. We will also cover gravimetric analysis, equilibrium chemistry,
titrimetric methods of analysis, spectroscopy, chromatography, and electrochemistry. Quizzes
testing a general understanding of these topics will be given at the end of each organized
section/chapter.
The overall goal of this course is to equip you with needed skills while teaching you the core
concepts of analytical chemistry. I will incorporate common terminology used in the field of
analytical chemistry and will reference the text when appropriate. I will provide ways that I find
to be easier for solving problems that are not in the text. You are more than welcome to use the
approaches utilized in the text; however, these techniques will not be extensively covered in class.

I am not giving exams, but rather 9 quizzes during the semester. The idea is that I have divided
the material into smaller sections that should allow each student to study the topic as we go and
then demonstrate an understanding of the material in a shorter time frame. This will allow me to
see where the class is with the information and will identify students earlier on that might be
struggling. For the student, it gives you 9 quiz grades instead of 4 major exams and allows you to
have one drop during the semester. By dividing the material into smaller sections, it should also
make studying the material easier.
In an attempt to be as fair and reasonable as possible, I will give partial credit for problems on
quizzes if the effort is demonstrated. My giving of partial credit in based solely on my discretion.
Write out your calculations or I cannot give you any credit. I reserve the right to stop giving
partial credit at any point.
No partial credit will be given for the final exam. The final exam is comprehensive and is the
standardized American Chemical Society (ACS) exam. Each question answered correctly is
worth 1.76 points. Therefore, 37 out of 50 questions should be answered correctly to receive a
100% on the final exam. Final letter grades will be based on the percentage of the total points
earned and on the tentative scale below.
The tentative grading scale is as follows:
≥ 86
82-85
75-81
71-74
61-70

For all quizzes and tests, The USC Aiken Honor Code is in full effect. If the instructor has
evidence that a student has violated this honor code for a particular assignment, that student will
receive a 0 for that assignment and a written letter detailing and documenting the student’s
actions will be sent by the instructor to the Executive Vice Chancellor for Academic Affairs
(EVCAA). Further information about violations of Academic Integrity can be found in the 20142015 USCA Student Handbook. You will be asked to sign the Honor Pledge on each examination.
Graded quizzes will be returned to you in a timely manner. You will not be able to keep the
graded quizzes. Therefore, for preparation of the final exam, you will want to review your class
notes and the homework problems.
Homework: Homework will be assigned regularly throughout the semester. I will not be taking
up the homework. I will provide you with a key for each assignment so that you can see the
correct answers as well as the correct procedure for solving the problem. Although the homework
is not graded, if you do not do the homework you will not be successful in this class.
Portable Electronic Devices: The use of any portable electronic devices, including cell phones,
MP3 players, iPods, etc., during class is not allowed for any reason unless prior approval has been
given to a student from the instructor or unless required for the course. If you are planning to
have any of these devices in class, they must be turned off and stowed away for the duration of
the class period. If a student is seen touching, holding, or using any portable electronic
device during a test period without the prior consent of the instructor, the instructor will
assume that the student is cheating and the test will be recovered and a 0 will be given to
that student for the assignment. A full description of this policy can be found in the USCA
Student Handbook.
Attendance: Attendance of all class meetings is expected, though excused absences are
understandable. However, regular attendance will be looked upon favorably at the end of the
semester for people with borderline grades. An attendance sheet will be passed around each class
period for you to sign. Any student who has more than 10% unexcused absences will be
assessed a one letter grade penalty off the final course grade. Any student who has been
absent (excused and unexcused) more than 25% of all class meetings will receive a failing
grade for the class. Unexcused absences on exam days will result in a grade of 0 for the exam.
Exams for people with excused absences must be made up as soon as possible at a time
convenient to the student and the instructor. Excused absences require a doctor’s note, a note
from a family member that includes a telephone number to check, a business note, or a receipt (in
the case of car problems). Please contact me with any questions.
Disability Statement: If you have a physical, psychological, and/or learning disability that might
affect your performance in this class, please contact the Office of Disability Services, B&E 134,
(803) 643-6816, as soon as possible. The Office of Disability Services will determine appropriate
accommodations based on documentation.
