Applications
Sodium sulfate anhydrous is used primarily for drying non-aqueous solvents by removing traces of water. It is used as a fining agent for molten glass, levelling agent in textile processing, and filler in detergents. It is also used in Kraft process for paper pulping, defrosting windows, manufacture of starch, glass, and soap.

Solubility
Soluble in water, glycerol and hydrogen iodide. Insoluble in ethanol and many organic solvents.

Notes
Anhydrous sodium sulfate is hygroscopic in nature, and absorbs moisture converting to the hydrated form. The hydrated form on heating gets converted back to anhydrous form.
