Nahco3 being weak base reacts
with carboxylic acid making sodium benzoate whic is soluble in
aqueous phase
Phenol being the weaker acid does not react with weak Nahco3 so it goes into organic layer with toluene .
But NaOH being strong base can react with phenol making sodium phenoxide ( a salt ) which is soluble in aqueous phase and can be easily separated using seprating funnel .
Toluene in organic phase ( ether ). Ether can be easily evaporated or leaving behind pure toluene .

An unknown mixture (dissolved in diethyl ether) contains only 2 of the following : benzoic acid, phenol, aniline and napthalene. You use the acid-base extraction method and want to identify the 2 compounds in your original mixture. 1) To separate the organic acid you add NaOH and to separate the organic base you add HCl.In both cases these extractions are followed by extractions with water. Why do we add water? Why is this step important? (A clear explanation please). 2)When...

Please, write out the balanced chemical reactions used to sequentially extract the carboxylic acid and the phenol from the organic phase into aqueous phases, and then precipitate them upon acidification of the aqueous phases, using the information below. 1st) You will prepare an ether solution (the organic phase) of the two compounds; any minor impurities are non-acidic and will remain dissolved in the organic phase throughout the extraction process. 2nd) You will extract benzoic acid from the organic (ether) phase...
