Food Colorant Experiment Madison Kuledge Charlie Crane Section 025 February 13, 2018 Introduction:
The color of a soft drink must be recreated. Using absorption spectroscopy, the color and concentration of a substance in solution can be determined. By comparing absorption of several standard known solutions, one can predict the concentration of an unknown solution based on a measurement of its absorption. This relationship between absorption and concentration is defined by Beer-Lambert’s Law and the equation A=ebc. To be able to determine the correct color of the food colorant we will be performing an absorption spectroscopy experiment. By doing this we will be able to know the concentration of the food colorant. The color of a soft drink can be recreated by establishing a known relationship between absorption and concentration of food colorant, then using this relationship to predict the concentration of dyes in the soft drink based on its absorption. When using absorption spectroscopy to be able to take measurements there’s a light source that is used that produces electromagnetic radiation that goes through the sample which is
