The purpose of this experiment is to apply Beer’s Law by analyzing samples provided by Q laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink. Procedure
Step #1: Convert %T (Table 1) to absorbance and prepare a Beer’s law plot using the data.
Step #2: Determine the concentration of M of the samples in table 2: A=ebc
B= 1.0 cm
Solve for E
(0.36) / (1875*1) = 1.92 x 10-4 m/L Molarity …show more content…
In the first exercise I concluded that batch 021015 did not meet legal requirements. In exercise two I enjoyed applying this concept to commercial item. I found that in Cool blue Gatorade the concentration of blue dye #1 contained in the drink is 3.6 x 10-4 M. Overall, this experiment was successful and satisfied the principle we were testing.
