TEXT: Required - An Introduction to Chemical Analysis I (available in Chem stockroom only,
           $10 cash/check w/ID)
      Recommended - Chemistry, The Molecular Nature of Matter and Change, 5th edition.
           by Martin Silberberg (Chem 201-202 textbook)

CALCULATOR: A simple calculator is necessary for completion of the laboratory reports and the
lecture exam. It must be capable of simple scientific functions including scientific notation,
squares/square roots, logarithms, and inverse logarithms.

safety goggles are available for purchase from the CGSA for $6 at time/location posted in the labs. Also,
remember that SHORTS, SHORT DRESSES, and SANDALS are NOT ACCEPTABLE attire in the
lab as they do not provide adequate leg and foot protection from accidental spills. Always read
each experiment’s procedures before coming to lab, complete the Pre-Lab questions, and follow
directions carefully. If you are unsure of any aspect of an experiment, ask your TA! Follow your TA’s
instructions on waste disposal for each experiment. Most waste solutions should be disposed of in the
waste containers provided and not down the sinks!

COURSE DESCRIPTION and OBJECTIVES: Chem 207 is an introductory course in analytical
chemistry and the first in a series of four half-semester laboratory courses that is designed to introduce
fundamental laboratory procedures from an analytical chemistry perspective and to loosely tie into
principles taught in Chem 201/202. Each of the four courses consists of a one-hour lecture and a three-
hour laboratory per week. The lecture is presented by the course instructor who is normally a member of
the Chemistry faculty, while teaching assistants, who are usually Chemistry graduate students, supervise
the laboratory sessions. The purpose of the lecture is to introduce important concepts and techniques
necessary for successful understanding and execution of experiments performed in the laboratory. Also,
the final exam will include material covered in the lectures. Therefore, lecture attendance is expected;
and success in the course is unlikely without it.

A schedule of laboratory experiments is included in the syllabus. You must read each experimental
procedure BEFORE your lab session, and a set of pre-lab questions must be answered prior to
beginning the experiment. Make sure you (1) know the purpose of the experiment, (2) understand the
concepts and procedures to be conducted, and (3) are aware of any safety concerns and special waste
disposal requirements. You must be familiar with and abide by all safety procedures posted in the lab
room and detailed in the laboratory manual. Proper clothing and eye protection (approved safety glasses
or goggles) are required at all times; students will not be admitted to the lab if clothing and eye
protection requirements are not met!

GRADING: Your grade will be based upon your performance on weekly experiments and on the final
exam. The experiments will contribute 3/4 of the grade, and the final exam will contribute 1/4. The lab
report includes the pre-lab questions and the actual lab report, both of which can be found in the
laboratory manual. The pre-lab question sheet must be completed by each student and approved by the
TA at the beginning of the lab before he/she will be allowed to begin the scheduled experiment. Lab
reports are normally due the next work day following the lab period and should be turned in to your TA.

Lab Reports (100 points each) – 600 points                  Grading Scale: 800-720 pts (90%)       A
Lecture Exam                  – 200 points                                 719-640 pts (80%)       B
                                800 total points                           639-560 pts (70%)       C
                                                                           559-480 pts (60%)       D
                                                                           479 or less (<60%)      F

REWRITE LAB REPORT POLICY: If a lab report has points deducted due to errors in calculations,
a student is allowed to correct it and return it to the TA. This must be done within one business day after
the graded report is returned by the TA. The original lab report must be attached to the corrected report,
or there will be no credit given for the corrections. The maximum possible grade is for such a “re-
calculated report” will be 90 points.

LAB REPEAT or MAKE-UP POLICY: The last week of the course is set aside to allow students to
repeat earlier experiments that they either missed or performed poorly. In general, only one lab
experiment can be repeated or made-up. However, for this experiment, the regular maximum of 100
points can be obtained, regardless of what the student’s earlier score was.

SAFETY: Safety is of utmost importance. Each student will be required to observe a safety video and
take a short safety quiz. Read each experiment’s procedures before coming to lab and follow directions
carefully. If you are unsure of any aspect of an experiment, ask your TA! In addition, nothing is to be
disposed of in the sink! Follow your TA’s instructions on waste disposal for each experiment.
CHECK-OUT: ALL students, regardless of whether continuing in the next course or not, MUST check
out and replace any lost or broken glassware during the final week of the course.
