Course Description and Objectives
This course is designed to demonstrate correct and safe laboratory techniques and performance
and develop quantitative laboratory skills. Titrimetric and spectroscopic methods will be used to
demonstrate proper methods of experimental measurements, record keeping, data organization
interpretation and report writing.
Attendance:
On-time attendance is required for every lab. In case of unavoidable absence, please contact the
instructor
Laboratory Notebook
Data must be recorded directly into the notebook and not on scraps of paper. There are 16
laptops in the analytical chemistry lab. One laptop will be assigned for each student for the entire
semester. Students might bring in their own laptops in the lab if they wish. Students must use
laptops to record data while working in the lab using appropriate programs.
You do not need to reproduce the lab manual. However, ALL the experimental details must be
recorded, e.g.,
 Size of equipment used (flasks, beakers, cylinders, pipettes, volumetric flasks, etc.)
 Drops indicator used, and which one
 Initial and Final balance readings, even if initial = 0.000 (units)



Same for all other measurements (What was the reagent? concentration?)
Data must be organized and complete enough for easy reproduction
Laboratory notebooks will be collected periodically and graded. The grade will contribute to
your overall laboratory grade.
Writing Lab Reports:
At the completion of an experiment, you are required to write a full or partial laboratory report. The
full laboratory report should have a cover page with the title of the project, the course name, number
and date of the report. It will also have the following subtitles:
 Introduction: 1 (or 2) paragraphs to introduce the purpose of the project the goal you set out
to accomplish.
 Experimental Procedure: A brief description of how you conducted the experiment
 Results and Discussions: Interpretation of your data and conclusions of the project.
For more information on writing lab reports go to the course moodle page (“Write like a
chemist”)
Repeated Experiments
Once an experiment has been completed and submitted for grading, it cannot be repeated.
Deadlines for Reports
In general, each experiment will take 1-2 laboratory periods. The results and reports will usually
be due about one week after the experiments are finished. Check the “Laboratory Schedule” for
exact deadlines.
Late-submission Policy
All unknown results and written reports are due at the beginning of the lab. Late reports will
lose 20% per day late and will not be graded if they are more than 3 days late.
Missed Lab Policy
Students having a valid excuse (funerals, illness, athletic events etc.) may reschedule a missed
lab, if possible, only if they notify the lab coordinator (Dr. Fazal, mfazal@csbsju.edu) before
the regularly scheduled lab.
Recalculated Results
In the event that the results submitted for grading for an experiment were miscalculated, one
recalculation will be permitted. The grade on that experiment will be the average of the original
and the recalculated grade.

Grading:
In this course you will finish five laboratory projects and one final project. Each project will take
about 1 - 2 laboratory periods and will count 100 points except the final project (150 points).
Some of the projects will be graded on the quantitative results only, others will be graded on the
discussion (report) of the experiment, and some on both the results and the report. In addition,
you will you will be taking five in-lab quizzes. The quizzes are designed to help you understand
the relevant chemical principles for the projects.
Final grades will be assigned on the basis of percentages rather than a curve. This means that any
number of students may earn any grade.

Academic Ethics:
Original work performed in good faith is assumed on all laboratory work. It is presumed that the
data you record and report in laboratory is your work. Scientific and scholarly misconduct includes
the following forms of inappropriate activities:
 Plagiarism (e.g., copying from other students, past reports, or writing of others etc.)
 Intentional misrepresentation of credentials
 Falsification of data
Failure to adhere to this code of ethics will result in prosecution to the fullest extent
(http://www.csbsju.edu/catalog/2007_2009/programs/rights/001.htm).
If you have not done something yourself, do not attempt to pass it as original work.
