CHEM 1211 Lab Contents CHEM 1211 & 1212 LAB - Dr. Kim's section Georgia Perimeter College - Dunwoody Campus Link to for General Information. The Lab Home Site above has useful information such as actual pictures (taken by our Lab Staffs) of experimental set-up/progress/results in color. Previewing of these materials should be helpful. In addition to the Laboratory Course Pack and the Lab Home Site, 'Laboratory Experiments' (H.R. McKelvy, Brooks/Cole, 2002), is recommended as a supplemental reference. Several Figures (Illustrations) and Pre-Lab Questions in the Manual, will be helpful in setting up some experimental apparatus and for pre-lab study.
From Fall of 2007, most of the Quizzes and Reports (16 out of 24) will be delivered online through the. From Fall of 2010, WebAssign is temporarily suspended, and all Online Lab Assignments (PreLab Quizzes in particular) will be delivered through (Online Web Learning). Laboratory Contents and Materials - The contents and order are subject to change from semester to semester.

Reference: Exp #5 Separation of Mixture ('Laboratory Experiments', H.R. Block and G.M. McKelvy, Brooks/Cole, 2002, p68) New Procedure (employed from 2006): The methods remain largely the same except the following difference from the old method: Salicyclic Acid (SA) is separated from copper(II) sulfate with Extraction with Diethyl Ether(DE), then the solvent (DE) is vaporized off completely in a hot water bath. Modification: from Fall 2010 Salicyclic Acid (SA) is separated from glass beads (or metal shots) to make the lab clean.
