Sodium Sulfate Anhydrous Uses and Properties

Views 760

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.

• Natural sodium sulfate is produced from naturally occurring brines and crystalline deposits found in California and Texas.
• It is also found as a constituent of saline lakes, such as the Great Salt Lake in Utah. Synthetic sodium sulfate is recouped as a by-product of different manufacturing processes.
• The two kinds of sodium sulfate has a few significant and helpful applications in different consumer products.
• In a survey of the top 50 basic organic and inorganic chemicals made in the United States, sodium sulfate ranked 47th in terms of quantity produced.

Sodium Sulfate Anhydrous Uses

• Sodium sulfate anhydrous is utilized to dry organic liquids.
• As a filler in powdered home clothing cleansers. 
• As a fining operator which expels small air bubbles from molten glass.
• Glauber’s salt, the decahydrate was used as a laxative that removes certain drugs such as acetaminophen from the body.
• For defrosting windows, in carpet fresheners, starch manufacture, and as an additive to cattle feed.
• In the manufacture of detergents and in the Kraft process of paper pulping.
