PROCEDURE (States changes made to the procedure. If no changes were done, say the procedure was followed as written.)
RESULTS (Fill in the data table. Write sample calculations and give a brief analysis of results.)
Table 1: Stock Dye Solution Data
| Dye solution | Peak (max) wavelength (nm) | Absorbance |
| Red | ||
| Blue | ||
| Yellow |
Table 2: Beer’s Law Data Table
| Concentration (M) | Wavelength(nm) from Table 1 | Absorbance |
| 0.1 | ||
| 0.2 | ||
| 0.4 | ||
| 0.5 | ||
| Best-fit line equation |
Insert graph from color chosen here
(from spreadsheet on Canvas)
Figure 1: Beer’s Law Graph
Table 3: Concentration of Extracted Dye
| Primary color | Wavelength (nm) from Table 1 | Absorbance | Concentration (M) |
| Secondary color | Wavelength (nm) from Table 1 | Absorbance | Concentration (M) |
Sample calculations: (Write the Beer’s Law equation used to find the concentration and define the variables. Show the calculations and include units.)
Analysis of results: (Write a short paragraph where you compare the spectrometer readings from the stock dye solution with the concentrations of the extracted dye from the Froot Loops color chosen. Also explain the trend observed in the graph from the Beer’s Law values.)
DISCUSSION (Answer the following questions correctly and thoroughly using complete sentences.)
- Did your solutions in Part I obey Beer’s Law? How do you know?
- Compare and contrast the features of a primary color spectrumwith those of a secondary color spectrum.
- Without using a spectrometer or any other instrument, how could you estimate the concentration of an unknown dye solution?
- Would you be able to use the line of best-fit from your Beer’s Law equation to calculate an unknown concentration of another primary color? Justify your answer.
REFLECTION (Explain personal contributions to the experiment as well as your partner’s contributions. Identify at least one limitation encountered and give at least one suggestion for improvement.)
