A New Year with a New Volume of Resources
The January 2015 issue marks the start of the 92nd volume of the Journal of Chemical Education and is now available online. This issue features colorful chemistry; using stories and writing to learn; demystifying chemistry literature; cost-effective activities and materials; experimenting with chromatography and natural products.
In A Colorful Solubility Exercise for Organic Chemistry, Christopher R. Shugrue, Hans H. Mentzen, II, and Brian R. Linton describe a discovery chemistry laboratory for introductory organic chemistry students to investigate the concepts of polarity, miscibility, solubility, and density. The simple procedure takes advantage of the solubility of two colored dyes in a series of solvents or solvent mixtures.
Other articles in the issue that explore color and chemistry include:
