Unformatted text preview: Beer’s Law Report Author: Spencer Stewart Co-Investigator: Nicole Dibona Supervisor: Xiaoyan Tu Sponsoring Organization: Chemistry 104B Section 101 Date Experiment was Performed: 24 January 2008 Date Report was Submitted: 31 January 2008 Abstract The molar absorptivity of the dye Yellow #6 was determined to be 12600 absorbance per cm*mol/L. This was determined by measuring the absorption spectroscopy of several standard dilutions of a stock sample of dye and plotting the points onto a graph. A line of best fit was calculated and was then used to determine the molar absorptivity of the dye Yellow #6. Introduction The objective of this experiment was to reintroduce students to the lab by having them prepare a series of standard dilutions from a stock solution, measure the absorbance of the solutions, and determine the molar absorptivity of a food dye at a specific wavelength. All experimental work and collection of data was shared by the co-investigator. Experimental The procedures for this experiment can be found in the Fundamental Techniques of Chemistry , 6 th edition, author Seven L.
