The purpose of this experiment is to separate a solution of an acidic and organic compound and purify its respective acidic product through the techniques of an acid base extraction‚ recrystallization‚ and use of Melt Temp (melting point range). The reaction of an unknown acid (3-chlorobenzoic acid) with diethyl and sodium hydroxide was observed‚ and the solution naturally separated into an aqueous and organic solution. The mixture of acid and organic solution was created and then separated through

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed
