Lab Outline
Description:
The lab will consist of 14 exercises performed by the students. Each lab will be related to the content of the material
covered in class.
Lab Materials:
General Chemistry I Lab Manual, 3rd Edition, by Muench
Safety Glasses (own or ones supplied by HCC)
Scientific Calculator
Lab Content:
Each week will begin with the students turning in their completed pre-lab assignment. Then, the instructor will
proceed with a brief explanation of the lab procedures for that particular week. Once all of that has been completed,
you will proceed with that week's lab exercise to its finality. All work, including data pages and questions, is to be
turned in before leaving.
Grading:
Grades will be determined by a combination of lab work and quizzes. The point values of each lab and quiz are found
on the lab schedule. The total point value is equal to 200 points or 20% of your overall grade.
Attendance:
Your attendance is mandatory for the lab section. There will be no opportunity to make up a missed assignment.
Anyone missing more than two lab periods can fail the entire course. If you know that you will miss a lab period for
any reason, please let the instructor know. The laboratory time is a three-hour time block – expect that each lab
period will meet for the allotted period. Anyone leaving early before completing all work will not receive full credit
for that lab period unless the instructor grants permission.
Quiz Format:
The four quizzes (see schedule for dates) will be based on the two previous laboratory exercises. It usually involves
being given a similar set of data to calculate a result just like you performed for the previous labs. Formulas will be
provided and you may use handouts from class, but you cannot use your graded labs or any notes.
Lab Report:
A laboratory report will be required for the spectroscopy lab. The specific instructions are contained in the lab
manual. The lab must be either typed or submitted electronically. If you do not have access to a computer (or
typewriter), then you should use a computer in our Library (for free). They are available days, evenings, and
weekends – see the Library for more information.
