    Problem How can you tell pigment separation by using Chromatography? Objective To prepare a chromatogram‚ separate pigments in a leaf and interpret the chromatogram. Hypothesis If I am to put a chromatography paper into a solvent‚ then it would separate the pigments depending on their Rf value. I think the pigments will separate in this order: Chlorophyll A‚ Chlorophyll BCarotene‚ and Xanthophyll. Introduction Chlorophyll is the molecule that absorbs sunlight and uses its energy

    Separation and Identification of Plant Pigments by Paper Chromatography Biology 1107L Introduction All living organisms require energy for their chemical processes. The ultimate source of this energy is the sun. Plants convert light energy into the chemical energy of sugars. During photosynthesis pigments are used to capture light energy. Pigments of green plants can easily be separated and identified using a technique called paper chromatography. The purpose of this

    Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase). In paper chromatography‚ a small amount of the mixture to be separated is placed close to the edge of a piece of paper. The edge of the paper is then immersed in a developing solution. As the developing solution ascends up the paper by capillary action‚ the. components

    Title:The Chromatography Process of Expo Markers Abstract:This experiment is to uncover whether or not the Expo Markers are homogeneous or heterogeneous mixtures. The experiment will conduct filter paper being slightly submerged in a container of water and inspected for pigmentation changes. In the experiment the pigments will rise up the filter paper once exposed to the water (solvent). After the experiment‚ it concludes that the mixture is a homogeneous mixture due to the chemical

    Chromatography: How can we separate a mixture? Purpose The chromatography lab is to understand how molecules with similar molecular properties can be separated with paper chromatography. These differences will be interpreted to see the distinction of separate chemical substances. Pre Lab Questions 1. Explain capillary action as it pertains to water and paper. Capillary action makes water draw up the paper. As paper absorbs water mixes with the solutions in the paper. 2. What is the
