Sodium Sulfate Common Organic Chemistry

Anhydrous sodium sulfate (Na2SO4) is typically used in organic chemistry as a drying agent. After aqueous extractions the organic layer always has a certain amount of water left in it. Adding anhydrous sodium sulfate removes this water by forming the sodium sulfate hydrate, which conveniently is also a solid allowing it to be filtered away.
