Lab Outline
Description:
The lab will consist of 15 exercises relating to the material in the book.
Required Textbook / Materials:
General Chemistry 162 Laboratory Manual, 1st edition, by Muench
Safety Glasses (Yours or ones supplied by HCC)
Scientific Calculator
Lab content:
Each week will begin with the students turning in their completed pre-lab assignment. A brief
explanation of the lab procedures for that particular week will follow. Once that has been
completed, you will proceed with that week's lab exercise to completion. Unless instructed
otherwise, all work is to be completed during the lab period and turned in that day.
Grading:
Grades will be determined by a combination of lab work and the lab final. The lab point values
will vary according to the difficulty of the exercises. The total number of points will be 200 or
20% of your overall grade at the end of the semester. There will be one laboratory report to be
completed in the semester.
Attendance:
Your attendance is mandatory for the lab section. There will be no opportunity to make-up a
missed laboratory assignment. Anyone missing more than two lab periods can fail the entire
course. If you know that you will need to miss an exercise for any reason, please let the
instructor know as far in advance as possible.
Lab Report:
One lab report will be assigned for this class and it is the third lab. You will be given
instructions in how to write this report in class. The lab report is due two weeks after the
conclusion of the lab activity for full credit. Any late lab reports up to the end of the semester
will be penalized 20% (5pts.). Students also have the option of turning in the data with complete
calculations only for a maximum of 10 of the 25 points possible.
Lab Final:
There will be one lab final at the end of the semester. This final has both a written and hands-on
component. The written part will be based on eight of the lab exercises previously completed
and you will only need to answer four of those questions. The hands-on portion will be based off
of the Qualitative Analysis from earlier in the semester and will require each student to identify a
total of four ions – one from each of the groups. A time limit of three hours is strictly enforced
for the combined written and hands-on exercise.
