To extract benzoic acid (C6H5COOH) from a chloroform solution, a suitable solvent to use would be a basic aqueous solution. One commonly used solvent for this purpose is sodium hydroxide (NaOH) solution. The extraction process is carried out by performing a liquid-liquid extraction, where the benzoic acid is transferred from the organic phase (chloroform) to the aqueous phase (NaOH solution).
