Calculating the Rf of every single pigment, in order to distinguish it and identify its solubility. This results in the plant being able to perform more photosynthesis because more photons of light are being absorbed which will result in more glucose being formed which will ultimately be stored as potential energy in the form of sugars during the winter months when photosynthesis doesnt occur.

Conclusion The experiment was carried out and it was proven that: Contact with all solutions in this lab. Chlorophyll A and B. You need just to specify all the demands for the work and indicate the deadline. If this lipid soluble solvent is present, as opposed to the water soluble solvent, then the lipid soluble pigments will move up the chromatography paper instead of the water soluble pigments.

If so, right you are. Chlorophyll a is the main absorber, meaning only it can pass the excited electrons to other molecules. Paper Chromatography Page 3 of 5. Pour about 2 mL of water into the test tube. The lipid soluble pigments will travel up the paper until their bonds between the water are so weak that it must stop following the movement of the solvent, and get placed at a certain height above the original concentrated dot.

9, Separation of Photosynthetic Pigment by Paper Chromatography I.

INTRODUCTION There are different types of components in plant pigments. The most important and abundant chemical pigment.

Paper chromatography is a process in which pigments are separated, from an initial concentrated solution, through the process of capillary action. A solvent is placed at the bottom of the paper. In paper chromatography, paper marked with an unknown, such as plant extract, is placed in a beaker covered with a foil containing a specified solvents.

The solvent carried the dissolved pigments as it moved up the paper. The pigments were carried at different rates because they were not equally soluble.
