Analyzing Sports Drinks with Beer's Law in a Green Chemistry Lab
Contributors
Summary
In this experiment, students use a Go Direct® SpectroVis® Plus Spectrophotometer to determine the concentration of FD&C Blue #1 food dye in various sports drinks through spectrophotometric analysis. By preparing dilutions of the dye and creating a calibration curve, students apply Beer's Law to measure dye concentrations accurately.
The activity emphasizes green chemistry principles by promoting the use of safer materials, minimizing waste, and substituting traditional metal ion solutions with food dyes. This reduces environmental impact while maintaining robust scientific inquiry. Students also explore how factors like solution composition can influence measurement accuracy.
