The analysis of alcohol has been widely used as the subject of many undergraduate laboratory experiments. The method of analysis varies from chromatographic techniques to spectroscopic techniques. An acidified solution of potassium dichromate has been used with visible spectroscopy to determine ethanol concentration of unknown samples. Infrared analysis has also been used to determine alcohol concentrations. This presentation will describe an undergraduate laboratory experiment that allows students to compare alcohol analysis using two different analytical methods.
