COURSE INFORMATION:
Course Description: This lab will involve hands-on investigations of topics including kinetics,
chemical equilibria, buffer systems, redox reactions, and qualitative analysis.
Course Corequisite: The corequisite for this course is General Chemistry and Qualitative Analysis II
(CHM 2046). Please note that students who withdraw from lecture or lab must withdraw from the
appropriate corequisite course.
REQUIRED TEXTBOOK & OTHER RESOURCE INFORMATION:
Textbook: General Chemistry II Laboratory Manual, Custom Ed., Slowinski, et al.
ISBN-13:
9781285886428
Other Required: Bound composition style notebook. The pages must be stitched, not glued, into the binding and
have no perforations. It can either be lined like notebook paper or have a grid like graph paper.
ATTENDANCE POLICY: Attendance will be taken at every lab meeting. Tardiness is not
acceptable. If you miss my discussion at the beginning of lab, you will miss important explanations,
and therefore would be unsafe in the lab. Under no circumstances will you be admitted to lab if you are
more than 10 minutes late, and you will be considered absent for that lab meeting.
Attendance must be reported for the first two weeks of the semester. If you are not attending this class
during this time, you will be automatically dropped from the course. The college-wide attendance
policy is included in the “Addendum to the Syllabus”, which should be read at the following web
address: http://www.spcollege.edu/central/asa/addendum.htm. At the 60% mark in the semester,
students will be evaluated for active participation in the course. If you have missed three or more lab
meetings, you will fail to meet my criteria for active participation and will be withdrawn and
given a “WF” for the course.
PLEASE NOTE: The lecture and the lab are co-requisites. If you withdraw from lecture, you must
also withdraw from the lab. If you withdraw from the lab, you must also withdraw from the lecture.
The last day to withdraw with a "W" is June 26, 2015. Failure to do drop before the drop date will
result in you receiving a final grade of "F." NOTE: instructors are NOT able to withdraw students.
TESTING / GRADING POLICY: The following weights will be given to assignments:
1.
2.
3.
4.
5.
You will have unannounced quizzes at the beginning of some lab periods. If you are
late to lab and miss the quiz, you will receive a zero for that quiz grade. Quizzes cannot
be made up. However, your one lowest quiz score will be dropped. Your overall
quiz average will count for 20% of your overall grade. You may use your lab
notebook (not lab manual) as a reference for any quiz.
Each week you will turn in data, calculations and ASA assignment. This will count as
your weekly lab report. Again, if you miss a lab, you will receive a zero for that lab
report grade. Lab reports cannot be made up. Your one lowest lab report grade will be
dropped. Your overall report average will count for 40% of your overall grade.
Your lab notebook will be graded at the end of the semester and will count for 10% of
your final grade.
The lab exams (midterm and final) will count together for 30% of your overall grade.
10% may be deducted from each lab report score for failure to follow experimental
procedures and safety rules. Always wear your goggles and clean up your glassware
and station when you have finished with your experiment.
You can calculate your grade as follows:
Quizzes
Reports
Lab notebook
Final
Your letter grade will be:
A 90 – 100 %
B 80 – 89 %
Percentage of Overall Grade
20
40
10
30
C 70 – 79 %
D 60 – 69 %
F < 60 %
REQUIRED ASSIGNMENTS EACH WEEK:
1- Read the introductory material pertaining to each experiment BEFORE the scheduled lab.
2- In your own words, write a detailed procedure for the lab in your lab notebook (BEFORE
coming to lab). You should be able to follow the procedure from your lab notebook.
3- You will also need to complete your lab “report”, which includes your data and calculations and
the advanced study assignment (ASA) from your lab manual. These reports are to be handed in
before your next lab and will be graded for accuracy and precision.
Special Accommodations
If you wish to receive special accommodations as a student with a documented disability, please make
an appointment with the Learning Specialist on this campus (712-5789). If you have a documented
hearing loss, please contact the Program for the Deaf at 791-2628 (V/TDD). If you will need assistance
