sodium bicarbonate NaHCO3
Other names: baking soda, bicarbonate of soda, soda ash, sodium hydrogen carbonate, sodium bicarbonate
Sodium bicarbonate is the monosodium salt of carbonic acid with alkalizing properties, which is a white, odorless crystalline powder. Sodium bicarbonate is a salt that decomposes to form sodium and bicarbonate in water. This decomposition alkalizes the solution, meaning it is able to neutralize the acid. It has a slightly salty and alkaline taste similar to soda (sodium carbonate).
