Abstract. Engaging non-science majors in a chemistry laboratory can be a challenge. Using project-based experiments, students relate the concepts that they are learning to everyday experiences. Herein, we describe a series of modules that can be used in part, or as a whole, for the total analysis of electrolyte beverages. The analyses described here include, sugar analysis through refractometry and hydrometry, electrolyte analysis via ion chromatography, dye analysis by thin layer chromatography, and citric acid analysis using liquid chromatography. Using the lure of a well-known sports beverage as a teaching tool, verifying the identity and quantity of items in this common item allows non-majors to engage with the material more fully.

Supporting Material. Supplementary information includes example laboratory protocols for determination of electrolytes in sports drinks (sodium and potassium) sample submission and data analysis, identification of dyes in sports drinks by thin layer chromatography, making and using a hydrometer and comparing it to a refractometer, and the measurement of sugar in sports drinks through refractometry. 2606KB
