OTHER TIMES BY APPOINTMENT (If these times aren’t convenient, please email or call me to
schedule an alternative time.)
Class Hours: Students must attend all scheduled four-hour laboratory periods. They are
responsible for any material covered or announcements made in their absence. Students will not
be allowed to work at any time other than their own scheduled lab period.
Course Description: Theory and techniques of chemical analysis including evaluation of data,
titrimetric, potentiometric, and spectrophotometric methods will be explored. Corequisite: CHEM
3210. Prerequisites: C or better in CHEM 1010/1011L and 1020/1021L.
Student Learning Outcomes: 1) to develop proficiency in the techniques by which various
chemical substances are analyzed quantitatively with respect to accuracy and precision; 2) to
know and understand the chemical reactions and the physical principles underlying the analyses;
3) to become familiar with and proficient in the use of the instruments and apparatus employed in
such analyses; 4) to become organized and efficient in carrying out the analyses and reporting the
results in written and graphical form, and 5) to learn to work safely in the laboratory.
Reference Texts:
Analytical Chemistry, Gary Christian, 6th ed., John Wiley & Sons, Inc., Hoboken, NJ, 2003.
Quantitative Chemical Analysis, Dan Harris, 7th ed., Freeman and Company, Inc., New York, NY,
2007.
Lab Manual: Quantitative Analysis Laboratory Manual, Spring 2013 edition (to be provided).
Materials Required: safety goggles or glasses, lab coat, hand towel, Sharpie marker
(recommended) and laboratory notebook (w/duplicate pages – available in book store)
Course Evaluation:
1. Lab Reports are written for each experiment conducted. They must be typed and include (a)
background/introduction (b) data collected (given in a table or using a report form which will
be provided) (c) discussion of results/conclusion. Guidelines are found in the lab manual.
-- Quant Lab Spring 2013 -- Page 1 of 4 --
A paper copy of the report is due at the start of class on the date indicated in the schedule. A
copy of your report must also be submitted to TurnItIn on Blackboard. Reports submitted late
(after collection at the start of class) will receive penalties of 5 points per day. Reports will
not be assigned a grade when submitted more than two weeks late. All scheduled lab
Experiments are to be completed. Any student who fails to complete the Experiments and
submit the required reports will receive and automatic grade of F for the course. There will be
no exceptions to this requirement.
2. Quizzes will be given at the beginning of the lab period. These quizzes will generally be
based on: 1) the lab Experiment just completed; 2) the lab Experiment just begun; and 3) any
other relevant or assigned material. Study questions for the Experiments and the quizzes are
found in the lab manual. A student who comes late on days when a quiz is scheduled will
forfeit the time missed due to his/her tardiness.
3. Lab Notebook consists of a permanently bound book with title, date, and objective. The
notebook must be brought to the lab each period and will be graded as indicated in the
schedule.
4. All data must be recorded directly in the lab notebook in ink. All information, class notes and
calculations are kept in the notebook and not scattered on notebook paper. Calculations are to
be done in the notebook, or excel spreadsheets must be taped into the notebook. The results
of the calculations should be summarized neatly for future reference. At the end of each lab
period, the data page must be initialed by your instructor and the tear-out carbon copy
submitted. (See the lab manual for more detail on notebook requirements.)
5. Lab Technique and Deportment includes cooperation in clean-up duties, observation of safety
rules, overall lab techniques and behavior in the lab. Violations may result in 5- or 10-point
penalties, and repeated violations may result in ejection from the lab or F in the course.
6. The Final Exam is a comprehensive, written exam.

Academic Misconduct
The CAS Academic Integrity Policy will be followed in this course. According to the policy,
academic misconduct includes, but is not limited to, the following:
1. Using unauthorized materials in completion of an exam, quiz, or assignment.
2. Assisting or gaining assistance from an unauthorized source during an exam, quiz, or
assignment.
3. Providing assistance to another student in a manner not authorized by the instructor.
4. Obtaining an examination or assignment in an unauthorized manner.
5. Using material from a source without giving proper citation.
6. Fabricating or altering data.
7. Submitting work to one class that is substantially similar to work submitted for another class
without prior approval from the instructors involved.
8. Submitting written work that is not completely one’s own or allowing others to submit one’s
work.
9. Destroying or altering the work of another student.
10. Committing any other violation of academic integrity as described in this syllabus.
Specific examples of academic misconduct include:
•
•
•
•
•
•
•
the use of a cell phone during an exam or quiz for any reason (even as a calculator);
talking during an exam or quiz;
using anything other than explicitly authorized materials on a quiz or exam;
attempting to read from another student's quiz or exam;
copying class assignments, including sharing files to analyze or present data;
using data that you did not collect in a report without proper attribution;
working with others on any assignments (in or out of class) when not authorized.
You are responsible for arriving on time for all quizzes or exams, as you will not be permitted to
begin after any other student has left the room. You are responsible for all written materials on,
under, and near your seat during quizzes and exams, so it is in your best interest to ensure that
the desk surface is clear of writing and that no extraneous papers are within your line of sight
(both when you begin and finish). Cell phones should always be off and inside a bag during a
quiz or exam; your instructor will not give you the benefit of the doubt if a cell phone is used or
visible. The CAS policy makes no distinction between the person receiving unauthorized
assistance (copying an assignment) and the person providing the assistance (allowing work to be
copied); both actions are academic misconduct.
All cases of academic misconduct will be reported to the CAS Dean's Office per Xavier's
Academic Integrity Policy. Any case of academic misconduct on assignments will result in a
grade of zero for the assignment and may result in a grade of F for the entire course.
Premeditated academic misconduct during an exam (for example, using a cell phone to text or
preparing a “cheat sheet”) will result in the student being asked to leave immediately and in a
failing grade for the course.
