Introduction
You’re coming off the field after a hard fought game against your rival team. You are needing a drink and you grab a blue Powerade off the managers table. The drink delivers the electrolytes needed to sustain throughout the rest of the day. Then, the athlete starts to think how much of his blue Powerade is actually made from the blue food dye. The food dyes have had a tremendous affect on global economics. In the early nineteen hundreds many of the food dyes were poisonous to the human body. The business owners saw an opportunity though by making the foods and candies more attractive to their customers. During this time safety started to become more of a concern and the government started to intervene and created some of the regulations you see today. In this experiment the class observed the absorbance spectroscopy of the food dye along with the concentration of the food dye in Powerade.

Then they start by using water to zero out the ultospec. When the ultospec is zero’d out they filled three fourth of a test tube up with each food dye being used. Each individual food dye was measured for its absorbance spectrum using the ultospec’s range of 400-750 nm. After getting the ranges of each concentration of stock solution the class then obtains a 5mL beverage sample with an unknown concentration of food dye. The class then gets a 50 mL of food dye stock in the color they were given. The class was then instructed to get five dry test tubes and number them one through 5. Using these test tubes they put in 10,8,6,4,2 mL of food dye and in inverse order put that amount in for dilution. From this the class was able to test the absorbance from this and calculate the
