I. REQUIRED TEXT
1.
Skoog, West, Holler, and Crouch. Fundamentals of Analytical Chemistry. 9th Ed.,
Brooks/Cole Thomson Learning. (ISBN 0-03-035523-0)
II. COURSE DESCRIPTION
A survey of the field of analytical chemistry and a detailed investigation of the standard methods
of quantitative determinations are presented in this course. Coverage areas include statistical
treatment of data, titrimetry, gravimetric, electrochemical, spectrochemical, and chromatographic
methods. All students registered for this course must also be registered for CHE 321L. Two
lectures are scheduled each week. This course is offered every other year as needed.
III. LEARNING OUTCOMES
Quantitative Chemical Analysis (CHE 321) investigates the methods scientists use to obtain
quantitative information about chemical systems. This course is taken by the student who has
successfully completed General College Chemistry I and II along with their laboratory
components (CHE 123, CHE 123L, CHE 124, CHE 124L) and Trigonometry (MAT 152).
Classical and fundamental techniques, equipment, and manipulations are introduced in the
laboratory portion of this course. Since this course deals with real systems taken from organic and
inorganic sources, students need to be familiar with basic organic chemistry concepts and
techniques. It is recommended that students complete at least one semester of organic chemistry
with laboratory prior to taking CHE 321.

Organization:
CHE 321 is divided into two parts:
Formal Lecture: Lecture topics will be those indicated in the lecture schedule. The student is
responsible for all subject matter covered in lecture and lab, any assigned readings, all assigned
problems, and anything the instructor says in class. The students' comprehension of covered
topics will be examined regularly.
Laboratory: A group of laboratory experiments will be performed on a schedule to be established
by the laboratory instructor. The specific details will be discussed during the check-in period on
the first meeting of the laboratory section. Read Chapter 2 in the lecture text prior to the first
laboratory experiment.
Upon course completion, students will be able to do the following:
1.
2.
3.
4.
5.
describe the fundamental steps involved in a chemical analysis
understand what chemical processes may be occurring during a given analysis
to assess the validity (integrity) of a given measurement and provide an understanding of
the results being calculated
demonstrate a working knowledge of statistics and their use in chemical analysis
to perform the requisite physical skills for performing quantitative chemical analysis
(laboratory)
IV. CORE VALUES:
Integrity – A principal goal of science is to organize and catalog knowledge. Scientists seek to establish
how the natural world functions by making and recording measurements about physical and chemical
phenomena. To assess the validity of a given measurement requires that scientists perform their duties in
an ethical manner so as to maintain the trust of society.
V. METHODS OF ASSESSMENT
a. Concept Quiz (10%)
A series of 5-10 minute quizzes serve to gauge student comprehension of module
topics in preparation to taking examinations. Quiz materials are taken from
assigned readings and homework. Quizzes are administered online or in-class.
b. Homework Problem Sets (10%)
The ability to solve problems lies at the heart of Quantitative Chemical Analysis.
Students are strongly advised to work all assigned problems to achieve
excellence in this course. Toward this end, a series of problem sets will be
administered. Problem sets are to be worked by the student individually and
submitted to the instructor for evaluation by the due date. The total number of
points for the problem sets and concept quizzes administered during a semester
will be equivalent to one examination grade.
3
c. Three Examinations (40%)
Examinations will focus on the theory and applications of quantitative chemical
analysis. Tests will be comprised of essay questions, numerical problems, and
“real world” analysis in the following areas: chemical, industrial, environmental,
pharmaceutical and medical applications.
d. Laboratory Performance (40%)
Quantitative Chemical Analysis is a laboratory-based course; students will write
formal laboratory reports that respond to “real world” analysis scenarios taken
from a variety of fields (e.g., chemical, industrial, environmental, and
pharmaceutical).
The following distribution will be used in assigning grades (decimal points will be rounded to the nearest
whole number at semester’s end)

VI. STUDENTS WITH DISABILITIES
Appropriate academic accommodations and services are coordinated through the Office of Disability
Services, which is located in the Student Activities Building. Students with documented disabilities who
may need academic accommodation(s) should email their requests to adaoffice@saintleo.edu or call
x8464.
VII. ACADEMIC HONESTY POLICY
The Academic Honor Code is published in it entirely in the Saint Leo University Catalog. The first
paragraph is:
As members of an academic community that places a high value on truth and the pursuit of
knowledge, Saint Leo University students are expected to be honest in every phase of their academic life
and to present as their own work only that which is genuinely theirs. Unless otherwise specified by the
professor, students must complete homework assignments by themselves (or if on a team assignment,
with only their team members). If they receive outside assistance of any kind, they are expected to cite the
source and indicate the extent of the assistance. Each student has the responsibility to maintain the highest
standards of academic integrity and to refrain from cheating, plagiarism, or any other form of academic
dishonesty as well as reporting any observed instance of academic dishonesty to a faculty member.
VIII. ATTENDENCE POLICY
Although attendance will not formally be taken, it is imperative that students attend class. The lecture
serves to reinforce the ideas described in the textbook. The lecture gives students opportunities to ask
questions of the instructor. Homework assignments, handouts, review questions, and other study aids are
distributed to students who attend the lecture. Finally, a significant portion of the scheduled examination
will come from the lecture material and assigned homework.
IX. LATE WORK / MAKE UP POLICY
It is the students' responsibility to promptly notify the instructor prior to any missed assignments or tests.
If the student is excused from an examination, the final examination score will be used to replace the
missing test grade.
UNDER NO CIRCUMSTANCES IS A MAKE-UP EXAM GIVEN. Unexcused absences from
examinations will result in a grade of zero.
5
Student Misconduct/Classroom Disruption
Saint Leo University students are expected to conduct themselves at all times in accord with good taste
and observe the regulations of the University and the laws of the city, state, and national government. All
University community members—faculty, staff, employees, students—have the right and obligation to
report violations of civil or University regulations to the appropriate University Vice President or
Associate Vice President of Academic Affairs. Should a University community member encounter a
disruptive student, the student shall be asked politely, but firmly, to leave the classroom (or wherever the
locus of disruption). A University community member has the authority to do this if the student is acting
in a disruptive manner. If the student refuses, the appropriate office shall be notified.
