0. A separatory funnel is the commonly used instrument for extraction. In it, two liquid layers are used for the selective precipitation of a solid from the liquid phase based on difference in density and solubility. The most common form of an extraction is an acid base extraction, which uses the different acidities of compounds to selectively
