the Extraction lab is to separate and purify benzoic acid‚ 2-naphthol‚ and naphthalene. These organic solids are purified by partitioning the solid in 2 immiscible solvents‚ diethyl ether and sodium bicarbonate or sodium hydroxide. II. Significance a. The significance of the Extraction lab is to purify Acetanilide benzoic acid‚ 2-naphthol‚ and naphthalene by determining the partition coefficient. This value is determined by dividing the solubility of the given solute in the extraction solvent
