Thin Layer Chromatography Plant Pigments Aj Klatch Kyle Tisi Mr. Edmondson AP Chemistry Table: 9/10 2/4/01 2/3 I. Abstract The purpose of this lab was to determine the rate of flow values (Rf=distance of component/distance of solvent) for certain pigments found in chlorophyll and carotene. For the chlorophyll, we observed the following five colors: yellow, orange, dark green, green, and light green. For the cartenoid, we observed the following five colors: yellow, auburn, purple, pink, and red. The solvent in both of our experiments traveled a distance of 6.8cm. We obtained the following Rf values for the chlorophyll. For yellow, Rf=0.89; for orange, Rf=0.78; for dark green, Rf=0.51; for green, Rf=0.49; and for light green, Rf=0.44. We obtained the following Rf values for the carotene. For yellow, Rf=0.89; for auburn, Rf=0.81; for purple, Rf=0.69; for pink Rf=0.51; and for red, Rf=0.49. The second part of this lab dealt with statistical treatment of four of our lowest Rf values...
