Sodium carbonate is a sodium salt of carbonic acid. It is domestically well known for its everyday use as a water softener. The manufacture of glass is one of the most important uses of sodium carbonate. It is also used as a relatively strong base in various settings. It is a common additive in municipal pools used to neutralize the acidic effects of chlorine and raise pH. It is also used as a primary standard for acid-base titrations because it is solid and air-stable, making it easy to weigh accurately. It is a food additive used as an acidity regulator, anti-caking agent, raising agent and stabilizer. It is used by the brick industry as a wetting agent to reduce the amount of water needed to extrude the clay. It is used in toothpastes, where it acts as a foaming agent, an abrasive, and to temporarily increase mouth pH. It is also used to create the photo process known as reticulation and also as raw material for detergent powder.
