CHEM A105L

General Chemistry I Lab is a laboratory course designed to teach the fundamentals of working with laboratory equipment, data gathering, analysis, and reporting.

The prerequisite for this course is (CHEM 105 with a minimum grade of C or concurrent enrollment).

All CHEM A105 labs are held in CPSB 312. You must attend the first day of labs and you must attend with your lab manual and goggles. If you miss the first day of labs, you may forfeit your space in lab. Both the lab manual and safety goggles are available through the campus bookstore. Labs start on January 14th, 2013. Students shall be dressed appropriately for lab or entry into lab shall be denied. Long-sleeved shirts, pants that go down to the ankles, and proper shoes shall be worn. (Lab coats are required only for Chem 104L students this semester. They are optional for all other lab students.) Review section 3d in the Chemistry Department's Teaching Laboratory Safety Agreement and Procedures for a complete overview of our dress code.

For your convenience, we've posted several files below that you may find useful at some point during the semester. Please check back frequently to remind yourself of what's available here. Some of our files are posted in PowerPoint format. Others are posted in pdf format. If you don't already have it, the Adobe Acrobat Reader can be downloaded for free.
