If you read the ingredients list for Cherry Kool-Aid it also lists RD&C Blue 1 as a dye present in the Kool-Aid mix. Why do we not have to worry about the content of the blue dye when determining the concentration of the red dye? The spectra for FD&C Red 40, Blue 1 and Yellow 5 are shown below.

Exactly 10.00-mL aliquots of a solution containing phenobarbital were measured into 50.00-mL volumetric flasks and made basic with KOH. The following volumes of a standard solution of phenobarbital containing 2.000μg/mL of phenobarbital were then introduced into each flask and the mixture was diluted to volume: 0.000, 0.500, 1.00, 1.50, 2.00 mL. The fluorescence of each of these solutions was measured with a fluorimeter, which gave values of 3.26, 4.80, 6.41, 8.02, 9.56, respectively. a. plot the data. b. derive a least squares equation for the data plotted in (a). c. find the concentration of phenobarbital from the equation in (b). d. calculate a standard deviation for the concentration obtained in (c).

Sally obtains a standard calibration curve for their assigned food dye by plotting absorbance versus concentration (in M) of known solutions and finds the following slope and intercept: y = 1.646x + 0.026 Note: Copying and/or posting this or other questions without the express written permission from Dr. Burke and the Department of Chemistry & Biochemistry at the University of Delaware is a violation of intellectual property copyright law. Sally finds that her original Kool-aid sample is too concentrated, so they dilute it by transferring 13.00 mL of the original Kool-aid sample into a new container and diluting to a total volume of 37.00 mL. If the absorbance of the dilute Kool-aid sample at the appropriate wavelength for their assigned dye is 0.950, determine the concentration (in M) of the assigned food dye in the original Kool-aid sample. Report your answer with three places after the decimal.

6. A sample of an alum was analysed by atomic spectroscopy and gravimetrically to determine its structure. A 0.1000 g of the sample when treated with BaCl₂ produced 0.0984 g of a white solid after drying to constant weight. Another 0.1000 g sample of the alum when heated at 105°C for several hours produced a weight loss of 0.04558 g while the % of K in the sample was determined by atomic spectroscopy to be 8.240%. Use these results to work out a formula for the alum. [M,/ g mole¹: K 39.10; Al 26.98; BaSO, 233.39; SO² 96.06; H₂O 18.0148]
