Sodium carbonate (or washing soda) is used as a cleansing agent for domestic purposes like washing clothes. Sodium carbonate is a component of many dry soap powders. It is used for removing temporary and permanent hardness of water.
As we know, anhydrous sodium carbonate has no water molecules. It's just Na2CO3. - When the hydrated sodium carbonate is strongly heated, it decomposes into water and anhydrous sodium carbonate.
Sodium Carbonate, Anhydrous is a water insoluble Sodium source that can easily be converted to other Sodium compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. Sodium Carbonate is generally immediately available in most volumes.
Sodium carbonate is also known as sal soda, washing soda, soda ash and soda crystals. It exists as a white powder, absorbs moisture from the air, and forms a strong alkaline aqueous solution.
