Sodium carbonate — Na2CO3 — is the sodium salt of carbonic acid. It is also known as soda ash, washing soda, and soda crystals. Chemically and physically, it is distinct from sodium bicarbonate, though there is some overlap in their applications, particularly in manufacturing and general industry.

  • Water treatment: It is used to treat industrial water by raising the pH of water to near neutral when injected in a water system.
  • Food and Nutrition: It is used as an acidity regulator, anticaking agent, raising agent, and stabilizer.
  • Personal Care: It is used as an abrasive, a deodorant agent , and an oral care agent.
  • Pharmaceutical: It has alkalinizing property. When dissolved in water, sodium carbonate forms carbonic acid and sodium hydroxide. As a strong base, sodium hydroxide neutralizes gastric acid thereby acting as an antacid.
  • Pulp and Paper: It is used in the process of separating cellulose fibers from the plant material.
