Sodium sulfate

The definition of sodium sulfate 
  Sodium sulfate (Na2SO4), a white, crystalline, water-soluble solid, Na2SO4, used chiefly in the manufacture of dyes, soaps, detergents, glass, and ceramic glazes.also called disodium sulfate, is used widely as an industrial chemical. It is an inorganic compound whose main ingredients are Sodium (Na) and Sulfur (S), and it occurs naturally as Thenardite. It can be created as a byproduct during certain industrial chemical processes, but even as a “waste” product, sodium sulfate is very useful.

Naturally Occurring Sodium Sulfate
  Sodium sulfate occurs naturally over millions of years of i iqneous rock erosion. When these rocks are gradually eroded by friction, the sodium content of the rocks is carried by water and eventually collects in natural basins, where it reacts with sulfur, which normally comes from eroding iron pyrite, volcanic sources or beds of qypsum. This  chemical reaction produces a precipitate, which is sodium sulfate. This mineral, which collects in crystalline deposits, was named Thenardite, in honor of Louis Thenard, a French chemist. It tastes salty and dissolves in water.

Manufactured Sodium Sulfate
  Sodium sulfate is often produced as a waste or byproduct during several industrial chemical processes. Manufacturing rayon, recycling battery acids, production of ascorbic and hydrochloric acids, cellulose and flue gas desulfurization are only a few of the processes which create sodium sulfate. The US generates about half of its domestically-produced sodium sulfate in this manner.

Biomedical Effects and Toxicity
  Absorption of sodium sulfate sulfate after ingestion in rats was investigated. (35)s-radioactivity excreted in urine during 24 HR indicated almost complete absorption from gi tract.determination in serum 2 hr after admin revealed 3-fola incr in sulfate concn.rapid&almost complete absorption of inorg sulfate occurs after oral admin in rats.

Summary
  As an industrial chemical, sodium sulfate is extremely versatile as well as inexpensive to produce. Its use has declined in recent years, as the trend in detergents and soaps has now shifted to concentrated liquids instead of bulky powders, which use more of this filler-type compound. However, it still has wide applications in other industries and will continue to be used in other, more innovative processes.
