solids and any solids of similar polarities will dissolve into the solvent. In a liquid-liquid extraction‚ two solids are separated by using two solvents of opposing polarity. Chemically active extractions are when two nonpolar materials are in solution‚ and one is chemically changed in order to change its polarity. In order to get the best yield‚ it is important to perform many small extractions rather than one large extraction. This is because some solubility in one layer will cause an equilibrium reaction
