How would you separate naphthalene and benzoic acid in an
ethyl acetate solution?
Answer / sudhir
In this solution of napthalene and benzoic acid in ethylacetate, add solution of 5% NaHCO3 and mix well. The benzoic acid will form a sodium salt due to neutralisation reaction and is dissolved in water layer. The ethylacetate layer will have napthalene dissolved in it. Evaporate/ distill out ethylacetate solvent, you will get napthalene white solid.
To the above aqueous layer add slowly Dil HCl solution till pH 1-2, benzoic acid will precipitate as white solid, filter it and dry to get pure benzoic acid.
