"Liquid-liquid extraction is based on the principle that if a substance is soluble to some extent in two immiscible liquids, most of it can be transferred from one liquid to other" (pg.636) What we did for liquid-liquid extraction is we added 25 mL of NaCl to remove any possible chance of water in our extract and clearing up any emulsion. Introduction Extraction involves dissolving a compound or compounds either from a solid into a solvent or from a solution into another solvent. Stripes of this solution were put on a filter paper and later, after dried placed into a beacon of solvent. Extraction, like recrystallization, is based on solubility factors. In the first experiment, the distribution coefficient that has been calculated is 7.24 in 1.0 mL of propanoic acid, 2.76 in 3.0 mL of propanoic acid and 1.92 in 5.0 mL of propanoic acid.
