Question

3. .Potassium carbonate is added to neutralize any acid that distills with the product. Write a chemical equation for this reaction.

4. Potassium carbonate is also added to salt out the organic product. What does it mean to “salt out the organic product”? What organic product did you recover with this technique?  

5. What is steam distillation? How was it used in this experiment?

6 .A common mishap in the lab is to confuse the aqueous and organic layers during an extraction process. If you separated two layers during an extraction and then forgot which layer was the aqueous layer and which was the organic layer, how could you figure it out?

Explanation / Answer

Q3

K2CO3(s) + 2H+(aq) --> H2O(l) + CO2(g) + 2K(aq)

Q4

K2CO3(s) --

salting will favour extraciton coefficient distribution

Q4

steam distillation --> it is a distillation technique which uses vapor differenc ein order to separate volatilve vs. least volatile material.

It is called vapor, sicne vapor is used in order to cool/heat materials

It is typically used for very specific material separation, very useful in laboratories for distillation depiction
