Unformatted text preview: Distance Unknown Leaf Pigment Traveled (mm) DistanceTraveledinmm _ een chlofoh 11 _— _—-__ ”—— Solvent Front: 110mm CONCLUSIONS Write a scientific conclusion for the following questions. Each question requires its own conclusion supported by data from the lab. 1. In task 1, which pigments had stronger attractions to the solvent (dissolved better) and which pigments had weaker attractions to the solvent (did not dissolve as well)? The plants with the higher rf values will be more soluble since the pigments were able to travel farther. In other words, this means that the pigments that dissolves more moved up the strip of paper more. For example, in this experiment the carotene and xanthophyll were the two pigments that dissolved the most. While the other pigments that did not move as high up the paper strip had weaker attractions. In conclusion the xanthophylls and anthocyanins were the weaker attractions because they barely moved up the paper strip. 2. In task 2, what pigments were found in your unknown leaf. Use both Rfvalues and physical observations to support your claims. Pigments like chlorophyll, anthocyanin, and carotene were found in my unknown leaf. The different colors, and shades on the strips determined what these different pigments were, as well as the If values. Therefore the higher the Rf value, then it will not be as polar whereas the lower Rf value then it will be more polar. In conclusion, this means that' since the anthocyanins did not move as much they had a low Rf value, which means that are polar. ...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
