Conclusions The purpose of this experiment was to observe extraction of dimethoxybenzene and benzoic acid. Extraction is the separation of a substance from one phase by another phase. It's based on the principle of equilibrium distribution between two immiscible phases, one of which is aqueous and the other being an organic solvent. Extraction is accomplished by shaking the mixture of the ...
