In which layer would you find ammonium salt of an organic compound, and why?
-
Describe the procedure you would use in the laboratory to determine which layer organic and which layer is aqueous. (Assume you don’t have access to physical constants for the solvents being used.)

Why is sodium sulfate added after an extraction?
Homework Answers
1.Due to more ionic character the ammonium salt of an organic compound will be found in the aqueous layer for more solubility in it.
2.To determine which layer is organic and which is aqueous we should add water drop by drop from a bottle.Now if the aqueous layer is on top then the water drop would immediately get dissolved and increase the volume of upper aqueous layer. So the other layer is organic.
Also if the aqueous layer is beneath the organic layer the water drop will bubble through the organic layer and come to the aqueous layer under it and mix with it. So from that we can understand which one is what.
3. After aqueous extraction, the organic layer always has a certain amount of water left in it. So by adding anhydrous sodium sulfate, this water is removed by forming sodium sulfate hydrate, which is also a solid allowing it to be filtered away.

Explain why the most polar compound layer stays in the organic layer, while the less polar compounds go into the aqueous phase. (This is for a liquid-liquid extraction) The most polar compund is caffeine and the solvent is ethyl acetate. I know it has to do with the caffeine not being able to deprotonate but I’m still confused and would like more information on why is can’t deprotonate.

1. What experimental difficulty would you encounter if you had neglected to include a drying step before evaporating the ether solution of the neutral organic compound? 1b. An extraction procedure specifies that an aqueous solution containing dissolved organic material be extracted twice with 10-mL portions of diethyl ether. A student removes the lower layer after the first extraction and adds the second 10-mL portion of ether to the upper layer remaining in the separatory funnel. After shaking the funnel, the...
