Part 3: Extraction With An Aqueous Base

Extraction with Potassium Hydroxide

Extract solution A2 three times with aqueous 1M KOH, using 2 mL each time for a total of 6 mL.

This video shows a large test tube with a colorless liquid. A second liquid is added that forms a separate layer below the first. A pipet is then used to mix the two layers by drawing up the lower layer and expelling it into the top layer. The layers are allowed to separate and the pipet is used to remove the lower layer. This process is repeated two more times.
