Record the absorbance readings from the spectrophotometer: keep this data for your records, the data you submit for the post-lab report must be typed up in Excel. Table 7-1. You will make three graphs, one for each extract Graph Generate an xy scatterplot (follow the instructions provided). Post-Lab Questions 1. What was the solvent for the chlorophyll extract? What was the purpose of the “blank” tube containing acetone? 2. If your experiment worked properly, you should see two peaks for spinach. Record the ranges of the wavelengths of these peaks and their colors. What do these two peaks indicate? 3. Look at the lowest points of your graph for spinach. Record the range of the wavelengths of the lowest points and its color(s). What does this low point indicate? 4. When do the green leaves show the least absorbance’s? How does this relate to colors used for photosynthesis? 5. How do the spectra indicate the season in which the extracts were collected?
