Extraction can be done in your organic chemistry lab using these two main pieces of At the top of this, this has an opening through which you can pour in liquid. (liquid–liquid extraction, LLE), to solid If the aqueous feed contains < 30% acetic acid, liquid-liquid extraction is usually a more economical solution than distillation for removal and recovery of acetic acid because the operating costs associated with distilling away the water far outweigh the capital costs of the liquid-liquid extraction process equipment. Upon addition of an oxidizing agent, leaves system is an example of liquid-solid extraction, and one can think of many such examples where components migrate from a solid phase to a liquid phase and vice versa. If the material to be extracted into the liquid is very soluble, simple stirring or shaking of a suspension of the solid in the liquid, followed by gravity filtration to remove insoluble impurities will suffice. Complexed iodine, soluble in water as triiodide, forms a brown solution in the denser aqueous layer while free iodine forms a faint pink color in the organic solution. This technique can be used to separate covalent molecules from ionic compounds in an aqueous solution or suspension. extraction from tea leaves involves an acid/base liquid/liquid extraction (Oneota, 2003) .
