Interpretation: Evidence for an ester is indicated by disappearance of the organic layer (if any), and the appearance of a precipitate upon acidification This reaction tests for the presence of an aromatic ring It can only be used for compounds that do not dissolve in sulfuric acid

(i) Litmus turns red and a white precipitate with silver nitrate(aq)(drop on end of glass rod), if the mixture is poured into water you may detect a 'pleasant' ester
