A discovery chemistry laboratory has been developed for the introductory organic chemistry student 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, and the diffusion of colors can be easily visualized. The clear and obvious results help promote an immediate understanding of the relevant concepts, as well as providing a memorable foundation to draw upon in future experiments.
