Sodium sulfate is an important compound of sodium, when anhydrous, it is a white crystalline solid of formula Na2SO4.
Na2SO4 is chemically very stable, being unreactive toward most oxidising or reducing agents at normal temperatures.
It is a neutral salt, which forms aqueous solutions with pH of 7.
Sodium sulfate has unusual solubility characteristics in water, in the presence of NaCl, the solubility of Na2SO4 is markedly diminished.
Applications:
Sodium sulfate is as a filler in powdered home laundry detergents.
Another major use for Na2SO4 is in the Kraft process for the manufacture of wood pulp. Organics present in the "black liquor" from this process are burnt to produce heat, needed to drive the reduction of sodium sulfate to sodium sulfide.
The glass industry also provides another significant application for sodium sulfate. It is used as a "fining agent", to help remove small air bubbles from molten glass. It also fluxes the glass, and prevents scum formation of the glass melt during refining.
Sodium sulfate is important in the manufacture of textiles. It helps in "levelling", reducing negative charges on fibres so that dyes can penetrate evenly. Unlike the alternative sodium chloride, it does not corrode the stainless steel vessels used in dyeing.
Glauber's salt, the decahydrate, was formerly used as a laxative. It has also been proposed for heat storage in passive solar heating systems.
Other uses for sodium sulfate include frosting windows, in carpet fresheners, starch manufacture and as an additive to cattle feed.
In the laboratory, anhydrous sodium sulfate is widely used as an inert drying agent for organic solutions; Na2SO4 is added to the solution until the crystals no longer clump together.
