Register to read the introduction… PROCEDURE.1 Using wax paper, 0.4003 g of Berry Blue Kool-Aid was measured out on the analytical balance and added to a 100 ml volumetric flask. Then distilled water was added to fill the flask to the volume mark. The flask was stoppered and mixed thoroughly. Using a volumetric pipette 1.00, 2.00, 3.00, 4.00, 5.00, and 6.00 ml of solution was added to six different clean and dry test tubes. To each of those test tubes was added enough distilled water to equal a total of 6.00 ml of solution in each test tube. The absorbance of each solution was taken at its lambda max of 629nm and recorded.

For the cherry flavor, using wax paper, 0.1109 g of Kool-Aid was measured out and the steps were repeated. The absorbance of each solution was taken at both lambda max of 503nm and 629nm because the cherry flavor contains both the blue 1 and red
