Acid Base Extraction Flow Chart Benzoic Acid

Acid-base extraction is a commonly used technique in organic chemistry to separate compounds based on their solubility in different solvents. Benzoic acid is a common organic acid that can be extracted using this method. In this article, we will provide a detailed flow chart outlining the steps involved in the acid-base extraction of benzoic acid.

To begin the extraction process, the benzoic acid is first dissolved in an organic solvent such as ether or dichloromethane. The mixture is then treated with a strong base, typically sodium hydroxide, which converts the benzoic acid into its water-soluble salt form. The salt is then extracted with water, where the benzoic acid is recovered by acidifying the aqueous solution with hydrochloric acid.
