Course description: Students will explore a variety of chemical reactions and
methods of determining reaction products. Emphasis will be placed on data
collection and analysis, and developing the lab skills required for upper-level
courses. Experiments will cover a range of topics, including methods of
measurement, chemical and physical properties of compounds, chemical reactivity,
colligative properties, reaction kinetics, and qualitative and quantitative methods of
analysis. Writing skills are emphasized in the lab reports.
Prerequisites: Grade of C or better in CHEM 1110/1110D/1011L or CHEM
1010/1010D/1011L.
Corequisites: CHEM 1120/1120D
Course objectives:
1) To develop reasoning and problem-solving skills using physical properties of
compounds as an analytical tool.
2) To learn how to apply the scientific method to problem solving.
3) To master the basic laboratory skills needed to enter advanced chemistry
courses.
4) To learn how to write the results of an analysis in a scientific format.
Materials required:
1. Chemistry Lab Manual
2. Safety goggles and lab coat
3. Non-programmable calculator
Course requirements:
Attendance is required for all scheduled labs during the time for which the student
is scheduled. It is the general policy that no make-up labs are allowed. In the event
of an absence, a student is responsible for doing and turning in the work that she or
he missed. Any student who misses more than 2 labs will receive an automatic grade
of FE.
Loboratory safety: Safety glasses and a lab coat are required. Safety glasses must
be worn for the duration of the lab. Food and drinks are not allowed in the lab.
Backpacks are not allowed on the floor or bench tops around your work area for
safety reasons.
Pre-lab Assignments: Each week there will be pre-lab questions and/or an
experiment outline to complete before your lab meets. For multi-week experiments
you will do one pre-lab assignment/outline for each lab.

Laboratory Lecture: Each week, at the beginning of lab, there will be a pre-lab
lecture of important information for the experimental work of the day. Be on time to
hear the pre-lab lecture.
Course evaluation:
Each week students will take a quiz covering the experiment they did the previous
week. Quizzes will be worth 20 pts each and will be administered before each
experiment. Each student will also write a report on each experiment and complete
any post-lab questions/homework assignments. Reports and questions will be
worth 50 points. There will be a comprehensive final exam worth 200 points.
Course grades will be assigned on a 10-point scale:
A 90-100%
B 80-89%
C 70-79%
D 60-69%
F below 60%
CELL PHONES, PAGERS, iPODS AND OTHER SIMILAR ELECTRONIC DEVICES ARE
NOT ALLOWED IN THE LABORATORY. FAILURE TO COMPLY WITH THIS RULE
WILL RESULT IN YOUR REMOVAL FROM THE ROOM.
Academic Misconduct
The following statement is found in the Xavier Faculty Handbook:
If a student's test, examination paper, laboratory report, term paper, or other written
assignment gives evidence of not being completely his/her own work, he/she may be
given an F for the course. A student who communicates with anyone during the course
of an examination or test, unless he does so with the permission of the instructor, may
be immediately dismissed from the room and given an F. Such communication includes
attempts to read from another's paper. If a student is found to have brought study
materials into the examination room without the instructor's permission, it may be
assumed that he/she intended to use such materials unlawfully, and he/she may be
penalized accordingly.
Any form of academic misconduct will not be tolerated. Most students have a pretty
good idea of what is considered cheating on an exam or quiz. However, many have a
hard time distinguishing what is acceptable from what is not acceptable when it
comes to writing reports in this course. A few things to keep in mind:
1) It is never acceptable to falsify lab data. If, while analyzing the results of your
experiment, you determine that your data cannot be correct, do not change it! It is
expected that you will, on occasion, not successfully perform an experiment and that
your data will not be correct. When this is the case you should focus on trying to
explain what might have gone wrong.
2) Do not use someone else's report as a guide for how to do your own report. Your
report MUST be your own work. Even if you don't "copy" someone's report, looking
at it to get ideas for writing your own is not acceptable. Keep in mind, also, that in

such situations the person who allows someone to look at his or her paper or who
provides answers to others in some other way is considered equally guilty.
