Question

I am supposed to pick from the steps at the bottom which would fit best in steps 1-3 in using a separatory funnel.

You have found that the pain killer, acetaminophen, has an absorbance in the UV range of light and want to use it as a test compound for your measurement technique. The suggested procedure involves the use of unfamiliar glassware, a separatory funnel. Look up a separatory funnel and describe how it will be used to reach the equilibrium of drug solubility in the two solvents.

Step 1: blank

Step 2: blank

Step 3: blank

------ Possible Steps -------

Pipet off the top layer to separate the two solvents. Open and close the stopcock to remove the air bubble. Open the stopcock at the bottom to separate the two solvents. Swirl the separatory funnel carefully so that the two phases do not mix. Combine the two solvents and drug in a beaker before pouring into the separatory funnel. Shake the funnel so that the drug reaches equilibrium between the two solvents. Add the two solvents and drug to the separatory funnel

Explanation / Answer

1. add the two solvents and drug to the separatory funnel.

2. shake the funnel so that the drug reaches equilibrium between the two solvents.

3. pipette off the two layer to separate the two solvents.
