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

Exp. 2 Separation of Three Compounds by Extraction Introduction: The purpose of this experiment is do demonstrate the proper procedures of extraction and to develop a practical understanding of this method. In this experiment‚ extraction is used to separate a known acid‚ base‚ and neural compound from each other. The first two compounds undergo proton transfer reactions in the presence of acids or bases. Acids RCOOH‚ like benzoic acid‚ was deprotonated to form RCOO-. Bases RNH2‚ like ethyl 4-aminobenzoate

Chem 1211L Mrs. Amy Cook February‚ 9 2011 Lab report on separation of mixtures Purpose- The purpose of this lab is to separate or isolate the desired product from large amounts of solvent and by-products. It is also followed by a purification step that removes trace amounts of other substances from the final product. One of the experimental techniques that we used in the lab to separate or purify mixture is fractional crystallization. In the experiment we used fractional crystallization to resolve
