You have an organic acid, organic base, and a neutral organic compound all together in a solid mixture. What steps would you take, in order, to isolate the organic acid? 1. 2. 3. 4. Dry the solution in the beaker with sodium sulfate, filter, and evaporate off the solvent. Dissolve the crude solid ether and place in separatory funnel. Add 3M NaOH(aq) and shake and vent, then transfer ageous phase to a separate beaker. Repeat two times. Rinse the organic phase with brine and transfer to a beaker. Add 3M HCI(aq) and shake and vent, then transfer ageous phase to a separate flask. Repeat two times. To the combined aqueous extracts, add 6M HCI(aq) until the solution is acidic. To the combined aqueous extracts, add 6M NaOH(ag) until the solution is basic. Filter to collect the solid.
