Answer questions and show your work clearly. No credit will be given for or ambiguous work. In the experiment of extraction from methylene chloride solution of benzoic acid and acetanilide, benzoic acid (C_6 H_5 COOH) was extracted with a solution of sodium hydroxide. Please write the chemical equation for the step to mix two solutions, methylene chloric (CH_2 Cl_2) solution with aqueous solution of sodium hydroxide (NaOH). Which chemicals are in both layers? Please identify them with the names and lagers. What can you do if you do not know which layer is the organic layer the aqueous layer is an extraction experiment? Addition of HCl(aq) to the aqueous layer of extract resulted white precipitate. Please write the chemical equation of this step.
