Objective: The objective of this experiment is to use acid-base extraction techniques to separate a mixture of organic compounds based on acidity and/or basicity. After the three compounds are separated we will recover them into their salt forms and then purify them by recrystallization and identify them by their melting points.

Procedure:
Extraction of Carboxylic Acid
A pre-weighed (0.315g) mixture of Carboxylic acid, a phenol, and neutral substance was placed into a reaction tube (tube 1). tert-Butyl methyl ether (2ml) was added to the tube and the solid mixture was dissolved. Next, 1 ml of saturated NaHCO3 solution was added to the tube and the contents were mixed separating the contents into three layers. Once this was completed the bottom layer was transferred to tube 2 using a pipette. Once in tube 2 the contents were washed with approximately 0.2 ml of ether and then the ether layer was discarded.

Extraction of Phenol
After the extraction of the Carboxylic acid,......
