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
Laboratory course investigates application of quantitative analysis techniques. Experiments
incorporate methods commonly used in industrial chemical, biological, or environmental
laboratory settings. Students are expected to be able to determine the quality of their own work as
well as the work of their peers. Techniques emphasized include chemical, separation, and
spectroscopic methods. All students registered for this course must also be registered for CHE
321. Two three-hour laboratories are scheduled each week. This course is offered every other
year as needed.
III. LEARNING OUTCOMES
Quantitative Chemical Analysis laboratory is an introductory course designed to teach the student
techniques that they can expect to use in the chemical, environmental or biological laboratory. A
thorough understanding of chemistry and mathematics to calculus are required. The laboratory
will introduce fundamental techniques and manipulations used in chemical analysis. The student
will learn how to judge the quality of their own work and others. This laboratory will:
1. Teach the principles of chemical analysis and teach the thought progression used to
establish which type and what quality of analysis is needed.
2
2. Teach the practical aspects of solution chemistry and the use of chemical equilibria in
quantitation.
3. Teach the principles of separation and speciation of materials. Introduce the tools of
chromatography and spectroscopy for quantitative analysis.
4. Teach the computational skills needed for analysis and introduce the use of computer
techniques for data acquisition and evaluation.
5. Teach the basic physical skills needed for good laboratory practices. Teach safe
laboratory practices and introduce the concepts of SAFETY FIRST.
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. Laboratory Reports (75%)
The laboratory is inherently an active learning process. Two laboratory sessions will be
given weekly. Students will be assigned an analytical problem and be expected to
develop an analysis procedure. Participation in the design and implementation of actual
analysis will be carried out as an active learning process. Teams will be formed and their
quality assessed based on the precision, accuracy and time required for analysis.
Quantitative Chemical Analysis is a laboratory course. The course cannot be
successfully completed without performing laboratory analysis and reporting the results
of the determination. Each week’s experiments will require a report that covers the
procedure that was used, the results of the experiment, and comments on how the
determination could be improved. Laboratory sessions must be done under faculty
supervision. Reports are due a week after completion of the experiment, unless
otherwise specified by the instructor. Late reports will be docked 10% per day.
b. Laboratory Notebook (20%)
Each student will maintain a laboratory notebook. The lab notebook is the primary record
of your experiments performed throughout this class. All information, including data and
notes should be entered directly into the notebook. This information should not be
written elsewhere and later transcribed into the notebook. All entries should be made
using blue or black ink. It is advised to not use ink that will bleed or run when exposed
to moisture (i.e. gel pens). Pencil, white out, and erasable ink should not be used. If a
mistake is made, it should be corrected by drawing a single line through it, entering the
correction after the mistake, and initialing the change. Do not scribble or scratch out the
mistake, as it should still be legible.
A proper laboratory notebook is one from which a given laboratory experiment can be
repeated. Another chemist, chemical engineer or chemical patent lawyer should be able to
read your notebook and understand what you did and the results you obtained.

Details about the type of laboratory notebook, format, and data presentation are discussed
in the handout Guidelines for Keeping the Laboratory Notebook in the laboratory
orientation.
c. Preparation (5%)
Student’s preparation for the laboratory will be assessed weekly based on experimental
design, safety assessment and promptness in carrying out the analysis. Weekly
preparation will count as 5 % of the final grade.
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 laboratory. This
setting allows students to reinforce the ideas described in lecture by doing real-world science. The
laboratory gives students additional opportunities to ask questions of the instructor.
IX. LATE WORK / MAKE UP POLICY
Laboratory reports are due a week after completion of the experiment, unless otherwise specified
by the instructor. Late reports will be docked 10% per day.
UNDER NO CIRCUMSTANCES IS A MAKE-UP LAB GIVEN. Unexcused absences from
laboratory will result in a grade of zero.
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.
