Sodium carbonate or soda ash, Na2CO3, is a sodium salt of carbonic acid. It is a white crystalline compound with a cooling alkaline taste, and found in the ashes of many plants. It is produced artificially in large quantities from common salt. It is used in the manufacture of: glass, chemicals such as sodium silicates and sodium phosphates, the pulp and paper industries, the manufacture of detergents and for the treatment of water. It is also used as an alkaline agent in many chemical industries.
