sodium carbonate monohydrate molecular weight

Sodium carbonate (Na2CO3) is the inorganic salt with the chemical formula Na2CO3. It is produced by combining sulfuric acid and calcium chloride to produce NH3 and then heating it with coal. This produces a large amount of Na2CO3.

It is mainly used as a pH adjuster in food products and water treatment. It is an effective corrosion inhibitor, which also prevents rusting in water tanks and pipes.

The molecular weight of sodium carbonate monohydrate is 2.54 g/cm3. It has an anhydrous and decahydrate form, which can be converted to the monohydrate by heating.

This hydrate can be easily broken down to sodium hydroxide in acidic solution, and is a common component of detergents, soaps, bleaches, toothpastes and cosmetics. It is also an antacid, reducing stomach acid and relieving heartburn.

It has antibacterial and antifungal properties, and is often used as a microbial growth inhibitor in foods. It is an important ingredient in pharmaceutical formulations for injection, oral and rectal applications.

Other uses include:

It is a component in the Solvay process of making soda ash. Originally, it was extracted from the ashes of plants grown in sodium-rich soils, which were different from ash of wood that was used to make potash.

It is also a component in evaporites, mineral deposits formed when seasonal lakes evaporate. Natrite, a rare mineral form of sodium carbonate, is mined from evaporites in Egypt where it has been used for centuries to prepare mummies. Trona, trisodium hydrogendicarbonate dihydrate, is a mineralogical form of sodium carbonate that occurs in ultra-alkaline pegmatitic rocks.
