Oct 30, 2023 · What is it? Sodium carbonate (Na2CO3) is the sodium salt of carbonic acid. 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. Sodium carbonate is commonly used as a water softener and is used to make glass.
Sodium Carbonate Formula. Sodium carbonate is a diazonium salt of carbonic acid with the chemical formula Na2CO3. It is also known as Soda crystals, soda ash, washing soda. This inorganic compound is water-soluble and when dissolved in water, it forms carbonic acid and sodium hydroxide. In its pure form, it is a white powder and odourless.

Sep 23, 2019 · Sodium carbonate is a stable, non-toxic odorless white powder that absorbs moisture and forms a strong alkaline aqueous solution. Sodium carbonate monohydrate (Na 2 CO 3 H 2 O) has an added molecule of water and is often used as a buffer. Two thousand years ago, the Romans used soda ash for making bread, glass, and various other products.
