Data Trial 1 2 Food Coloring Blue Yellow Mixture Chlorophyll Extract Table 8.3 Peaks of unique features of the spectrum orange Blue and oxinge Blue and sud 1. Describe, in detail, the spectrum of each food coloring sample. With the mixture, can you clearly distinguish the characteristics of the blue and yellow food coloring? Explain. 2. Consult a reliable resource to identify the major absorbance peaks of chlorophyll a and chlorophyll b. Examine the absorbance vs. wavelength graph for chlorophyll. Does your graph clearly show these absorbance peaks? Are there other, undefined, peaks on your graph? Identify them and speculate about what caused these peaks.
3. How did your tests of the absorbance of the blue and yellow food colored solutions compare with the tests of the chlorophyll extract? 4. If distilled water had been used as the calibration blank for the chlorophyll test, would it have affected the absorbance measurements?
