What is Sodium Sulfate?

Sodium sulfate (Na2SO4) is the sodium salt the sulfuric acid.

You are watching: What is the correct formula for sodium sulfate

Anhydrous sulfate is a white crystalline solid additionally known together the mineral thenardite, while the decahydrate Na2SO4.10H2O has actually been well-known as Glauber’s salt or mirabilis.

Na2SO4.7H2O is reinvented to mirabilite when it is cooled. Mirabilite is the natural mineral kind of the decahydrate. About two-thirds the the world’s production of salt sulfate is obtained from mirabilite. That is likewise produced from spin-offs of chemical processes such as hydrochloric acid production.

In 1625, Johann Rudolf Glauber uncovered the salt sulfate from Austrian spring water, over there so the hydrate type is well-known as Glauber’s salt. As result of its medicinal properties, he called it sal mirabilis (miraculous salt).

The crystals were offered as a general-purpose laxative, until the 1900s. Through reaction through potassium carbonate or potash, Glauber’s salt was supplied as a raw product for the industrial production that soda ash in the 18th century. In the nineteenth century, the demand for soda ash to be increased, for this reason the large scale Leblanc process which produced artificial sodium sulfate ended up being the principal technique of soda ash production.

At dietary levels, excretion is greatly in the urine. Sulfates are found in every body cells, v the greatest concentrations in connective tissues, bone, and also cartilage. Sulfates pat a role in several important metabolic pathways, consisting of those affiliated in detoxification processes.

There are two species of sodium sulfate natural and also by product, additionally known together synthetic.

Natural sodium sulfate is created from naturally developing brines and also crystalline deposits found in California and Texas.It is also found together a constituent of saline lakes, such as the good Salt Lake in Utah. Artificial sodium sulfate is recovered as a by product the various production processes.Both varieties of salt sulfate have several important and useful applications in various consumer products.In a survey of the optimal 50 straightforward organic and inorganic chemicals made in the unified States, sodium sulfate ranked 47th in state of quantity produced.


Sodium sulfate is widespread in occurrence and also is a common component the seawater and many saline or alkaline lakes.Economic to make reservation of natural sodium sulfate are approximated at 3.3 billion lots worldwide.With civilization production of natural sodium sulfate averaging around 2.6 million loads per year, gives are sufficient to meet anticipated demand for several centuries.The amount of synthetic sodium sulfate is dependence on the longevity that the production firms recovering by product sulfate.Surface depressions or lakes that have actually no outlets and are fed by feather waters flowing end volcanic rocks include sulphide minerals often yield soluble sulphide salts that room oxidized by call with the waiting to create sulfates.

Uses of sodium Sulphate

Sodium sulfate is offered to dry organic liquids.As a filler in powdered home laundry detergents.As a fining agent which removes little air balloon from molten glass.Glauber’s salt, the decahydrate was offered as a laxative i m sorry removes certain drugs such as acetaminophen native the body.For defrosting windows, in carpet fresheners, strength manufacture, together an additive to cattle feed.In the to produce of detergents and in the Kraft procedure of file pulping.

Frequently request Questions

What happens once sodium sulphate is reacted with barium chloride?

Sodium sulphate reacts through barium chloride in a double displacement reaction to type barium sulphate and also sodium chloride. The chemical equation for this reaction is provided by:

BaCl2 + Na2SO4 → BaSO4 + 2NaCl

This reaction occurs due to the fact that sodium sulphate is one electrostatically bonded ionic sulphate.

Write a short note top top the solubility of sodium sulphate in water

At a temperature that 0 levels celsius, the solubility of anhydrous salt sulphate in water is 47.6 grams per litre. As soon as heated come 20 levels celsius, that is solubility sharply increases to 139 grams per litre. Finally, in ~ a temperature the 100 levels celsius, the solubility of salt sulphate in water coincides to 427 grams per litre.

How have the right to sodium sulphate be prepared?

Sodium sulphate have the right to be all set via the Mannheim process, which is provided by the complying with reaction:
