Sodium bicarbonate, also known as baking soda, has a CAS number of 144-55-8 and its molecular formula is NaHCO₃. It is an inorganic compound, presenting as a white powder or fine crystals, odorless, salty in taste, and soluble in water. Its aqueous solution is slightly alkaline. It decomposes easily upon heating, slowly decomposes in the humid air, generating carbon dioxide. It begins to decompose at about 50℃ and completely decomposes when heated to 270℃. It undergoes intense decomposition upon contact with acid, producing carbon dioxide.
Sodium bicarbonate is widely used in industries such as chemical engineering, medicine, food, light industry, and textiles, as well as in people's daily lives. It holds an important position in the national economy.
