General Chemistry Lab Manual

The links below will allow you to download the current lab experiments for Chemistry 111 and 112. These experiment handouts are used by all lab instructors. All experiments are in Acrobat PDF format. If needed, download and install the free Adobe Acrobat Reader software on your computer.

For experiments which include Excel spreadsheets, copy the spreadsheet to your computer (save the file on your computer or on your Z: drive), then work with it on that computer. Note: Instructions in the lab manual have been designed for use with Excel 2007. Older versions of Excel (Excel 2003) will still be able to open these files, but the lab manual instructions will not work well with older versions of Excel.
