Chem 101 Laboratory exercise:
Here are some shots of OJC's Chem 101 Introductory laboratory section. In this lab the students are applying their newly learned separation techniques. The exercise consists of separating solid particulates (mud) from a water sample (simulated Arkansas river water) by using gravity filtration, vacuum assisted filtration and centrifuge separation techniques. In addition the students separated an unknown color mixture into its "building components" by using paper chromatography.
