About Solvent Extraction
Solvent extraction separates a substance by distributing it between two immiscible liquids according to its solubility and partition coefficient. The topic covers selecting suitable solvents, use of a separating funnel, acid-base extraction, phase identification, drying and evaporation, and why several small extractions usually recover more solute than one large extraction.
