Sodium sulfate - Wikipedia
Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product. It is mainly used as a filler in the manufacture of powdered home

Role of sodium sulphate as additive in mobile phase ...
11.02.2005 Sodium sulfate is highly hydrated and ties up a lot of water molecules. This lowers the solubility of other molecules less able to compete for with sodium sulfate for water molecules. The result is increased retention when employed in conjunction with a hydrophobic surface (I assume your question is in regards to reversed phase or HIC retention modes). Of

Experiment #6 – Isolation of Caffeine from Tea Leaves
The anhydrous sodium sulfate will absorb the small amount of water that is dissolved in the dichloromethane and small amounts of water from the aqueous layer that may have gotten into the flask by accident. [If you collected a substantial amount of emulsion in the Erlenmeyer flask, the sodium sulfate should help to “break” the emulsion. You may need to separate the
