lab was to determine the food dyes present in a selected beverage‚ their concentration‚ and then replicate the solution within a 20% margin of error. The beverage we chose was Gatorade Frost Riptide Rush. A spectrometer was used to determine which food dyes were present in the sampled beverage‚ red 40 and blue 1 were determined to be present. The next step was to determine the concentration of the dyes‚ this was done by testing the absorbance of the red 40 and blue 1 dyes at varying concentrations;
