Required materials: The textbook for the course is “Chemistry and Chemical Reactivity” by Kotz,
Treichel and Weaver. An inexpensive scientific calculator capable of handling scientific notation and
simple mathematical functions is required. You do not need a graphing calculator or a programmable
calculator for this course. The lab manual will be provided to you during your first lab period. Safety
goggles that cover the whole eye are required and you will not be allowed in lab without safety goggles.
Course objectives: The faculty of UW-Eau Claire has stated eleven academic goals for the baccalaureate
degree. This course should provide students an opportunity to develop (a) an ability to inquire, think,
analyze; (b) an understanding of numerical data; (c) an understanding of science and scientific methods.
The specific topics of the course include the structure of atoms, the structure and bonding of ionic
compounds and of molecules, stoichiometry, types of chemical reactions and the physical and chemical
properties of matter.
Attendance policy: Attendance at lecture meetings will be monitored and students with excessive absences
will be referred to the Dean of Students. Students will not be evaluated based on attendance. Students are
solely responsible for material and announcements made in lecture. Make-up quizzes and exams will not be
given. Students missing quizzes or exams because of an excused absence (proper documentation required)
will be given a prorated grade for the missed quiz or exam. Attendance is mandatory at laboratory periods.
Students missing labs because of an excused absence must make arrangements to attend another lab section
to complete the laboratory work.
Homework: A list of suggested homework problems for each chapter is included in the tentative course
schedule on page 3. This list is a starting point; most students should identify and work similar problems
for extra practice. These homework problems will not be collected or graded, but they are still important.
Quizzes and Homework: Short (approximately 15 minute) quizzes will be given on every other Friday
during lecture as outlined in the course schedule, and somework sets assigned on the alternate weeks will
be graded by you in class on the other Fridays. The quizzes and homework sets will be based on material
presented in lecture and the suggested homework problems, and may include problems based on the
previous week's laboratory experiment.
Exams: Three in-class 50-minute exams will be administered throughout the course of the semester as
outlined in the course schedule (see below.) the final examination is cumulative, and is scheduled for May
12th at 3:00 p.m. All students must take the final examination to earn a grade above "F" in this
course. Exam questions will be based on material covered in the assigned readings, lecture and in
laboratory.
Laboratory: The laboratory is an important part of the course and students must complete all laboratory
assignments to pass the course. Points will be awarded in lab for completion of required activities, post-lab
assignments based on the lab activities and in-lab practical exercises. Although most experiments will be
completed in pairs or groups, some in-lab practical exercises will be performed individually. Furthermore,
some quiz and/or exam questions will relate directly to lab experiences. Therefore, all students are strongly
advised to become active participants in the laboratory sessions. The final laboratory experiment is a
challenge problem that will be done individually, with only eight students in the laboratory working
different problems at the same time. The Challenge Problem is attached to the end of this course outline.
Students with disabilities: Any student who has a disability and is in need of classroom accommodations,
please contact the instructor and the Services for Students with Disabilities Office in Old Library 2136 at
the beginning of the semester.
Academic Integrity: I consider any academic misconduct in this course as a serious offense, and I will
pursue the strongest possible academic penalties for such behavior. The disciplinary procedures and
penalties for academic misconduct are described in the UW-Eau Claire Student Services and Standards
Handbook in the section titled, “Chapter UWS 14—Student Academic Disciplinary Procedures.”
Course grades: Points can be earned as follows:

25 pts each
Homework sets
7 pts each + 1 free point for the semester with no absences

Revised 1/08, AJG
Chemistry 103 Lab Practical Exam
The scenario:
The end of the semester has arrived and the general chemistry lab requires cleaning before next semester.
Unfortunately, you find three unlabelled samples and, in order to dispose these chemicals properly, you
must identify them. All you know is that the chemicals (shown in the groups below) were used during the
course of the semester.
Your assignment:
You will establish the identity of the three unknown samples. Your task is divided into the following parts:
1. Identify the group for each unknown. Your unknowns will be from three different groups. (Example: A
K+ salt, a halogen, and an acid.)
2. Identify the specific compound from each group. (Example: KCl, Br2 and HCl)
3. Explain the reasoning that enabled you to come to these conclusions.
K+ salts
KCl
KBr
KI
halogens
Cl2
Br2
I2
Ca2+ salts carbonates
hydrocarbons
alcohols
CaCl2
Na2CO3
hexane
methanol
CaBr2
K2CO3
heptane
propanol
CaI2
(Each unknown will be provided to you in the form of either
a 1.0 M aqueous solution, a pure solid or a pure liquid.)
acids
HCl
H2SO4
6M HCl(aq), 6M NaOH(aq), 6M H2SO4(aq), 6M HNO3(aq), I2(aq), Br2(aq), Cl2(aq), NaI(aq), NaBr(aq),
NaCl(aq), water, cyclohexane, methanol, ethanol, propanol, pentane, hexane, heptane, acetone, all the
solids in the solubility grid, sodium hydrogen carbonate, citric acid monohydrate, malic acid, lithium
carbonate and potassium carbonate will be available for chemical tests. You will have your own laptop
computer and set of Vernier probes available for measurements. For this assignment, identification of an
unknown or group by the process of elimination is permitted. For example, if you know the unknown must
be a “halogen” and prove that it is not Cl2 or I2, you may conclude that it is Br2.
Prior to your lab period: This exercise is based entirely on experiments in the 103 lab manual. You will
have the rest of the semester to prepare for this assignment. You may work with other Chemistry 103
students (in your lecture section) and consult your instructor while developing your problem-solving
strategy. You MAY NOT seek help from other faculty or anyone not enrolled in your lecture section of this
course.
During your lab period: You will be given 75 minutes (including clean-up time) to identify your
unknowns. A copy of this sheet will be provided to you. You will not be allowed to bring any notes, your
lab manual, or your textbook into the lab. You will work alone and may not talk to the other students in the
lab. While you may ask the instructor questions, he/she may not be willing to help, as in any exam
situation.
