Experiment Separation of Organic Compounds by Acid-Base Extraction Techniques 5 A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction techniques to separate a mixture of an organic acid‚ a base‚ and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds

Symmetry Symmetry has two meanings. The first is a vague sense of harmonious and beautiful proportion and balance.[1][2] The second is an exact mathematical "patterned self-similarity" that can be demonstrated with the rules of a formal system‚ such as geometry or physics. Although these two meanings of "symmetry" can sometimes be told apart‚ they are related‚ so they are here discussed together.[2] Mathematical symmetry may be observed * with respect to the passage of time; * as a spatial
