After pouring out the ether layer into a beaker and adding anhydrous sodium sulfate‚ all that remained in the funnel was the neutral extract. Isolation The preliminary steps in the isolation of the organic acid and organic base required volumes of approximately 10 mL and 8mL respectively of the inorganic acid or base (HCl or NaOH) in order to initiate the cloudy appearance in solution.
