Na2CO3, commonly known as sodium carbonate or soda ash, is a white, odorless powder that is highly soluble in water. It is primarily used in glass manufacturing, as it helps lower the melting point of silica, making the glass production process more efficient. Additionally, it serves as a cleaning agent and is found in various household products. Sodium carbonate also plays a role in the chemical industry, where it is used in the production of other chemicals, such as sodium bicarbonate and sodium silicate. It can be produced through the Solvay process, which involves reacting ammonia with carbon dioxide and sodium chloride.
