What is Solvent Extraction with pictures wisegeek

Jul 26, 2019 Solvent extraction is a method for separating a substance from one or more others by using a solvent It relies on variations in the solubilities of different pounds in different substances In most cases, the substance to be extracted, which may be a solid, a liquid or a gas, is dissolved in a liquid, along with other substances, and a liquid solvent is used for the extraction this is
