Unformatted text preview: Experiment 5 Proof of Alcohol Chemistry 1045L- Purpose: The purpose of this lab was to learn how to use a seperatory funnel and pyrex glassware for handling liquids. The lab showed how to separate liquids into two layers. Also this lab reinforced the basic techniques of weighing and calculations. Procedure: The procedure was followed according to this link: http://www.chem.fsu.edu/chemlab/chm1045lmanual/alcohol/report.html . There were no changes in the procedure. Data: Liquid Mass Grad.
