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.

Answer #1

Sodium sulfate is a drying agent used for removing water molecules in ether layer.

Sodium sulfate should be added to the ether layer till the clumping stops and it becomes free flowing. Thus option D is correct.
