Material Safety Data Sheets (MSDS) of all chemicals utilized in the laboratory can be
found at the following web site: http://hazard.com. E-copies are free of charge.
Approved eye protection used for the laboratory component of this class.
A simple scientific calculator without extensive memory functions (i.e. Texas Instruments
model 30, equivalent, or less sophisticated models).
Information Regarding CHEM 202 Lab: Your safety while conducting laboratory exercises is
of paramount importance. Your instructors and the Department of Chemistry will ensure that
you have access to all information regarding potential hazards associated with each
laboratory exercise. As students enrolled in a chemistry course with a laboratory component
you are responsibility too. The students’ responsibilities are to read and follow all the
Department of Chemistry Lab Safety Rules.

Material Safety Data Sheets (MSDS) of all chemicals utilized in the laboratory can be found
at the following web site: http://hazard.com. E-copies are free of charge. As a responsible
student you are required to learn more about the various hazards associated with the
chemicals and reagents that will be utilized in the laboratory.
Hands-on experience is a vital factor in learning chemistry. Great care must be taken in
using all equipment and reagents. The laboratory grade will be based upon your completion
of the experiments, lab reports, and lab quizzes. Since the laboratory experience is integral
to the overall course, failure to earn a passing grade in the lab will result in automatic failure
for the course.
Since you will be working in small groups, it is important that you keep your lab notes
separately from all other students. When a lab is completed, you must submit your own,
original report from the Laboratory Manual.
All take-home pre-lab quizzes are worth 5 points. The quizzes are given in the lab manual
for each laboratory exercise. The lab grade will be based on the best 10 out of 12 labs
quizzes and lab reports. There are NO MAKE UP LAB QUIZZES.
All labs are worth 20 points and the lab grade will be based on the best 10 out of 12 lab
reports. There are NO MAKE UP LAB REPORTS. Lab reports are due by 4:30 p.m. the day
after the lab session is completed. A penalty of five points per day will be levied for late labs.
Lab reports may be turned into the Teaching Assistant or at Currens 107 to the Teaching
Assistant’s mail box. Lab reports MUST BE marked with the following: student’s name,
course number (CHEM 202), lab section number, lab meeting time, and the TA’s full name.
Failure to include this information may result in a zero for the lab report.
Students enrolled in this course are levied a non-refundable laboratory usage fee of $35 to
cover the cost of consumable supplies utilized during the semester.
Lab work is an integral part of the CHEM 202 course. It is important that you study the
complete lab assignment BEFORE the day of the lab so that you are familiar with:
1. The lab procedure and can conduct the lab in a time efficient manner;
2. The equipment used and the lab techniques involved; and
3. The calculations used in the lab.
