Sodium carbonate naturally occurs in arid regions, especially in mineral sediments formed when seasonal lakes evaporate. Since ancient times, deposits of the mineral have been mined in Egypt, from dry lake bottoms. was utilized in the preparation of mummies but also in the early manufacture of glass.
Soda ash is used in glassmaking, in the production of sodium chemicals (sodium chromates, phosphates, and silicates), in the wood pulp industry, manufacturing soaps and detergents, in water softening and refining of oils and nonferrous metals. Its hydrous crystallized form is known as soda crystals, sal soda, or washing soda. Soda ash (Na2CO3) should not be confused with baking soda (sodium hydrogen carbonate or sodium bicarbonate, NaHCO3). The safety specifications for sodium carbonate can be considered less demanding than those for the related bicarbonates, due to its lower alkalinity.
Stability/Shelf life
Stable. Incompatible with powdered alkaline earth metals, aluminum, fluorine, organic nitro compounds, alkali metals, nonmetallic oxides, concentrated sulfuric acid, oxides of phosphorus.

Industry use
As a strong chemical base, it is used in the manufacturing of pulp and paper, drinking water, textiles, soaps, detergents, and as a drain cleaner. In addition, it can also be used for tissue digestion, in dissolving amphoteric metals and compounds, as well as a cleaning agent.
Consumer use
Sodium carbonate is used in food preparation as a food additive, anticaking agent, raising agent, pH balancer, and stabilizer. It is used in the production of sherbet powder, and as a vital component in Chinese and German traditional cuisine.
Solubility
Soluble in water, aqueous alkalis, and glycerol. Partially soluble in aqueous alcohol. Insoluble in CS2, acetone, alkyl acetates, alcohol, benzonitrile, and liquid ammonia.
