Liquid-liquid extraction (lle), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar) there is a net transfer of one or more species from one liquid into another. 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.
