Office Hours: M-Th: 9:00-9:30AM, T 3:00-5:00 PM, M Noon – 1:00 PM
Class Time: W: 1:00-3:50 PM
Class Location: ST-233
REQUIRED ITEMS: Electronic calculator with Log and Antilog functions. The calculator should be brought
to each class period.
WebCT: The experiments for this course are available through WebCT. Your instructor will tell you how to
access the appropriate WebCT course from the CSM website. It is the student’s responsibility to print a copy of
each experiment. Please note that each experiment includes an advanced study assignment that is due at the
beginning of lab on the day the experiment will be performed. Note: The order in which the labs are listed
on WebCT IS NOT the order is which they will be performed. See the schedule at the end of this syllabus
for the order in which the experiments are to be performed.
PREREQUISITES: CHE 1210 lecture taken in the same or a previous semester.
Course Description: Lab work includes computer-assisted data collection and analysis, lab techniques and
safety precautions during experiments in equilibrium, reaction rates, and titration. Students also perform several
qualitative analysis experiments.
Course Objectives: The successful student, upon completion of the course should:
a. have developed basic laboratory skills by performing qualitative and quantitative analyses;
b. have applied these skills to analytical determinations in stoichiometric relations, equilibrium
systems and kinetics problems.
Disabled Student Policy: If you have learning or other disability, which might affect your performance in this
class, please inform your instructor as soon as possible. Additionally, in order to verify your status and to
provide you with appropriate assistance and/or accommodations, you must contact Glennis Daniels-Bacchus in
the Learning Assistance Center.
Learning Specialist: Glennis Daniels-Bacchus is available in the LAC to assist any student, not just those with
a learning disability, with study skills, note taking, test anxiety, etc. Simply stop by her office or call her at
extension 7614.
Policy on Visitors in Class: Current college policy prohibits any person from being in classrooms except
students registered for the course, instructors, or officially invited guests. Specifically, this means that nonregistered students and children of students or instructors may not be present in the classroom during
instructional time.
Grading:
Lab Reports (best 9 of 10)
CPR assignments
100 points each
100 points each
Final Grades will be computed using the following scale:
>90% A, 80-89% B, 70-79% C, 60-69% D, <60% F
At my discretion the minimum percentage needed for a given letter grade may be lowered.
Lab Reports: The Lab Report for each experiment will consist of:
1. Advanced study assignment page(s); due at the beginning of the lab period (1:00 PM) on the day the lab is to
be performed,
2. The data and calculations page(s) (all calculations MUST be written out on a separate sheet), and
3. The post lab questions (if any).
If you do not turn in the advanced study assignment at the beginning of the lab period you will be expelled from
the lab for that lab period. Anyone expelled for this reason or due to violations of the Safety Policies WILL
NOT BE ELIGIBLE TO MAKE UP THE EXPERIMENT AND WILL RECEIVE A GRADE OF ZERO.
After completing the experiment, but before leaving the laboratory, the student must have her data sheet(s)
initialed by the instructor. Items 2-4 of the Lab Report will be due at the BEGINNING of the lab period
following the completion of the experiment. LATE LAB REPORTS WILL BE DOWNGRADED BY 10
POINTS FOR EACH LAB PERIOD (or fraction thereof) which they are late.
CPR: Calibrated Peer Review. These are online writing assignments in which you will write a directed essay
on a topic in chemistry. You will also review and evaluate the writing of others. More details will be provided
in class. To access the assignments go to the CPR website at: http://cpr.molsci.ucla.edu and log in. If you have
used CPR for a prior class at CSM use your username and password. If you are logging in for the first time you
will need your CSM student id (NOTE: IF the first digit of your CSM student id is a “0”, DO NOT include it
when you log in to CPR for the first time.) You will be assigned a CPR username. Follow the directions to
elect a password. See the Help sheet you were given. The deadlines for the CPR assignments are on the
schedule found later in the syllabus.
Attendance: Because of the unique nature of chemistry laboratory courses it is impossible to make up missed
labs. Missed labs earn a grade of zero.
Student Conduct: Plagiarism and other forms of cheating are prohibited by The Student Code of Conduct.
Plagiarism or any form of cheating will result in a grade of zero for the work in question. In addition the matter
may be referred to higher authority.

GENERAL EDUCATION STATEMENT
We consider "general education" to be a common body of values, skills, and knowledge to which all graduates with A.A. degrees
should be exposed and for which we may determine certain levels of competency. These values, skills, and knowledge are
representative of a common body of educational experiences that we view as vital for enabling our graduates to make rational
decisions in an increasingly complex society.
In taking this science course, the student can reasonably expect to be exposed to the following skills, and categories of knowledge. For
a more thorough listing of general education goals, the student is referred to the college catalog.
Mathematics
Graduates should be able to:
1. compute accurately using basic mathematical operations;
2. make estimates and approximations and judge the reasonableness of results;
3. interpret graphs, tables, and charts;
4. comprehend prose which contains mathematical information; and
Observation
Graduates should be able to:
1. conduct careful, thoughtful observations of objects and phenomena in science;
2. select and use appropriate instruments to measure and observe objects and phenomena;
3. describe their observations and measurements accurately using appropriate terms and units;
4. interpret and draw appropriate conclusions based on their observations and measurements;
5. evaluate the significance of the conclusions reached.
Reasoning
Graduates should be able to:
1. recognize valid and invalid reasoning;
2. understand and use inductive and deductive reasoning;
3. draw reasonable conclusions from information found in various sources (written, spoken, tabular, and
graphic);
6. identify, evaluate, and solve problems;
7. compare, contrast, and classify information and concepts
