What is the role of anhydrous sodium sulfate in experimenting extraction?

organic chemistry

thanks in advance=)

Answer:
Drying a wet organic.

Edit: as in removing water.
catalysis (guessing)
In extraction, we use solvents, aqueous medium. Water content will hinder in extraction and separation. Anhydrous sodium sulphate ,which can absorb upto deca mole of water, the extract will be anhydrous.
During solvent extractions sometimes the sample provided has water present in it. In order to get all of the desired analytes out of the sample and into the solvent you must remove the water. Water is also a good solvent so it soaks up some of the extractables. So in order to get 100% of the extractables you add large enough amounts of sodium sulfate to soak up all the water.
It is also useful in removing sample emulsion, which is really just water causing problems again by refusing to seperate from the sollvents fully.
