Extraction of benzoic acid
WebThis experiment involves the separation of benzoic acid from a more crude form‚ consisting of benzoic acid ‚ methyl orange‚ a common acid /base indicator‚ and cellulose‚ a natural polymer of glucose (Huston‚ and Liu 17-24). The technique that is used to perform this separation is called extraction. Extraction is a systematic process ... WebMore acid will be needed to recover benzoic acid 2)A 36 mg sample of an organic compound (MW=84 g/mol) is dissolved in 10 ml of water. This aqueous solution is extracted with 5 ml of hexane. Separation and analysis shows that aqueous layer after extraction contains 12 mg of the organic compound.
