ABSTRACT
Solvent extraction is another name for liquid-liquid distribution, that is, the distribution of a solute between two liquids that must not be completely mutually miscible. Therefore, the liquid state of aggregation of matter and the essential forces that keep certain types of liquids from being completely miscible are proper introductory subjects in a study of solvent extraction. Furthermore, the distribution of a solute depends on its preference for one or the other liquid, which is closely related to its solubility in each one of them. Thus, the general subject of solubilities is highly relevant to solvent extraction.
