Abstract

The title exercise is presented as a vehicle for gaining proficiency with a type of experiment that novice researchers often consider to be nearly impossible—the isolation and characterization of products from a chemical reaction performed on what would seem to be a prohibitively small scale. It is argued that (i) this experiment exposes students to important issues unique to scales this small and (ii) the skills developed are best learned with nonprecious materials and before they are critically needed. The enhanced self-confidence that accompanies this gain in expertise, in combination with the manipulation skills, makes this a particularly empowering experience and experiment.

  The Hendrix College organic chemistry laboratories were converted to microscale experiments in 1988 to minimize possible adverse environmental impact, increase lab safety, and decrease generation of waste and costs of waste disposal. As we became aware of ...
