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
