Sodium sulfate, anhydrate: Sodium sulfate is the sodium salt of sulfuric acid. When anhydrous, it is a white crystalline solid of formula Na2SO4 known as the mineral thenardite.
Sodium sulfate, anhydrous appears as white to off-white powder.
It is very soluble in water and insoluble in ethanol.
Sodium sulfate is a reagent used in large-scale applications such as dyeing and printing textiles, and the manufacture of glass and paper pulp.
It occurs in nature as the minerals, miabilite and thenardite.
Anhydrous sodium sulfate is frequently used in the drying of organic liquids. Sodium sulfate has been used in protein crystallization.
The effect of salts, including sodium sulfate, on the adsorption processes of proteins in hydrophobic interaction chromatography has been reported.5 Sodium sulfate has been used to investigate prion protein folding.
A protocol for the analysis of antibody -antigen interactions by sizeexclusion HPLC that incorporates sodium sulfate has been reported.
