During an extraction.. What does MgSO4or Na2SO4 do? How do you know if you have added enough MgSO4 to the organic layer? What must have occurred if you added to an Erlenmeyer flask containing a colorless solution and it all dissolved?
Homework Answers
MgSO4 or Na2SO4 are both drying agents that remove trace water from the organic layer during the extraction procedure.
when MgSO4 or Na2SO4 added to organic layer then they will clump up and stick to the flask. If all the water from organic layer absorbed then addition of excess MgSO4 or Na2SO4, they will be powdery and easy to swirl up.
so when we see that MgSO4 or Na2SO4 are begin to powdery and easy swirl up that is drying agent stirs freely without clumping then we understand that all the trace water is absorbed by drying agent.
What must have occurred if you added to an Erlenmeyer flask containing a colorless solution and it all dissolved?
when drying agent added to a colorless solution and it all disappears, then you added it to your water layer. there are no solid state seen in organic layer. so you add this colorless solution to water layer to re extract it.

How will you know how much Na2SO4 to add to dry the ether layer? A. When all of the liquid is gone you have added enough sodium sulfate. B. If the sodium sulfate looks "clumpy" you have added enough. C. All you need is a thin layer of sodium sulfate on the bottom of the beaker. D. When the sodium sulfate stops "clumping" and starts looking "powdery" you have added enough.

When using a drying agent to remove residual water from the organic liquid, how do you judge when enough drying agent has been added? O Enough drying agent has been added to completely absorb all of the organic compound so no liquid remains.

O Particles of drying agent are clumped together and stuck to the sides of the flask....
