To The Student:
Chemistry 112 is the second-semester general chemistry laboratory course
designed to accompany the second-semester lecture course, Chemistry 102.
It is assumed that students are concurrently enrolled in both the lecture
and laboratory courses. We hope that through this laboratory course you
will gain useful skills and knowledge that will complement what you will
be learning in the lecture course.
In this course you will be given instructions on additional useful lab techniques
and will gain additional experience in the treatment of laboratory data.
Through a variety of applications many concepts of both the first and second
semester of general chemistry lecture will be illustrated. To assist you
in gaining the most from this course we have, wherever possible: (1) selected
exercises with a wide variety of applied chemical principles, (2) designed
pre-laboratory instruction to assist you, and (3) arranged for a help desk
to provide help outside of the time that you are in lab. Lab office hours
will be held at the help desk in Room 415 of Heldenfels Hall. Check the
bulletin boards outside of Rooms 100, 401 and 413 for schedules of the help
desk, etc. You may also call the First Year Chemistry Electronic Information
Center at 862-3456 for information on weekly assignments, quizzes, etc.
Everyone associated with this course wants it to be enjoyable, instructive,
and meaningful. Please feel free to call upon us if we can be of assistance
during the semester.

First Year Chemistry Labs
You Will Need:
1. The laboratory manual (Measurement and Synthesis in the Chemistry
Laboratory, L. Peck and K. Irgolic).
2. The lab notebook (8 1/2" x 11", perforated alternating white
and yellow pages with carbon paper).
3. Approved eye protection. University and Departmental Regulations require
that splash-proof, chemical goggles be worn by everyone present any time
any experimentation is being conducted or any time chemicals or equipment
are being moved by anyone in the laboratory. (The Graduate Chemistry Fraternity
will be at the labs the first week of lab to sell suitable goggles). Failure
to wear goggles will result in expulsion from the laboratory for the experiment
involved. You may also wish to bring a calculator, a laboratory apron, or
a nonflammable lab coat. The textbook for Chemistry 102 will also prove
helpful. An apron or lab coat will be required if your shorts or skirt do
not cover your knees.
Policy on Safety and Breakage
Before working in this laboratory course, every student must read the "Laboratory
Safety" rules in the laboratory manual plus the Departmental Rules
and agree in writing to abide by these rules. It is imperative for your
safety that you and everyone around you strictly adhere to the Safety Rules.
Failure to comply with the safety regulations (e.g., by not wearing eye
protection at all times; by wearing open-toed shoes, short skirts or shorts;
by running an unauthorized experiment; or by removing chemicals or equipment
from the lab) may result in dismissal from the course or deduction of points
on your reports.
In this course you will be utilizing equipment furnished by the Chemistry
Department. It is your responsibility to properly maintain the equipment
while it is in your care. If equipment that has been entrusted to you is
not returned in satisfactory condition, you will be held responsible for
it.
Grading and Absence Policy
Absences: The schedule on the back of this sheet gives the date that
each experiment is to be completed. A make-up session is scheduled for those
students who have missed prior experiments due to university approved reasons.
Excused absences will need to be reported to your instructor in a timely
manner.
Data Sheets: A data sheet must be submitted at the end of the lab
period to receive a grade for that day's experiment. The data sheet may
not be graded in some sections; however, the Report Form for the corresponding
experiment will not be graded if the data sheet is not submitted the day
the experiment is conducted.
Reports: For each experiment you will receive a total score between
12 and 0. The Report Form is due the same day that the experiment is performed
unless indicated otherwise. The Report Form must reflect information obtained
by you while in the laboratory and recorded on your data sheets. The Prelab
Exercises associated with each experiment are due before you start the experiment,
unless specified otherwise on the "schedule." Neatness and completeness
of your data sheets and prelab exercises may be considered when points for
organization of data, etc., are assigned as a part of your Report Form grade.
Many instructors deduct up to 4 points from the Report Form for incomplete
data sheets and/or 4 points for incomplete or messy Prelab Exercises. Points
will be deducted for Report Forms not submitted on the date indicated. Reports
more than two weeks late will not be graded.
Quizzes: Quizzes (16 points each, usually 3 or 4 points per question)
are scheduled at various times during the semester. The quizzes will reflect
what you should have gained from previous weeks' experiments, what you should
master before beginning the current week's experiment, and your ability
to utilize techniques and concepts. You must take the final exam to obtain
a final course grade of D or higher. However, taking the final exam does
not insure one a grade of D.
Grades: At the end of the semester the scores on all quizzes, reports,
and written final (30 points) will be totaled for each student and the final
letter grades for the course will be determined based upon the ranking of
each student's total points compared to other students in that section.
For the past several semesters the average grade in every section has been
a mid-B. We do not expect the grade distribution to differ this semester.
Dishonesty: Students are expected to be the sole source for any work submitted
in their name or the name of a group designated by the instructor. The utilization
or submission of work of other students, tutors, or other agents not authorized
by the instructor is a violation of scholastic dishonesty policies and disciplinary
steps will be taken. Only authorized electronic or printed materials or
equipment may be used in or near the laboratory. Unauthorized programs,
materials, or equipment will be confiscated or destroyed.
