Sodium Sulfate Anhydrous Uses and Properties

Sodium Sulfate Anhydrous = molecular formula (Na2SO4) is the sodium salt of sulfuric acid.

Sodium sulfate is a white crystalline solid also known as the mineral thenardite, while the decahydrate Na2SO4.10H2O has been known as Glauber’s salt or mirabilis.

Na2SO4.7H2O is changed to mirabilite when it is cooled. Mirabilite is the regular mineral type of the decahydrate. Around 66% of the world’s creation of sodium sulfate is gotten from mirabilite. It is also produced from by-products of chemical processes such as hydrochloric acid production.

There are two sorts of anhydrous sodium sulfate natural and by-product, also known as synthetic.
