Sodium bicarbonate ( also called baking soda), a white solid with monocrystalline crystals and powder form. Sodium bicarbonate precipitates as a solid from this method:

Commercial quantities of baking soda are also produced by a similar method: soda ash, mined in the form of the ore trona ((Na3HCO3)2.H2O), is dissolved in water and treated with carbon dioxide. Further addition of carbon dioxide produces sodium bicarbonate, which at sufficiently high concentration will precipitate out of solution: The initial reaction produces sodium carbonate:

NaHCO3 may be obtained by the reaction of carbon dioxide with an aqueous solution of sodium hydroxide. It is produced on the scale of about 100,000 tonnes/year (as of 2001). NaHCO3 is mainly prepared by the Solvay process, which is the reaction of sodium chloride, ammonia, and carbon dioxide in water. NaHCO3 also has many applications in the leather industry, rubber and extinguishing substance. In addition to its direct uses for humans, NaHCO3 is also used for cleaning kitchen utensils, cleaning some positions that need to be cleaned because of highly corrosive properties, reacting with some substances, sprinkling on areas around the house to prevent some insects. NaHCO3 also help reduce the amount of oil on the skin, oily skin is the main cause of acne prone skin. Using directly: rub on the teeth to remove plaque and whitening tooth. In medicine, baking soda is also called salt drugs, used to neutralize acid, cure stomachache or detoxify acid Using as mouthwash Used to foam and increasing pH in effervescent tablet (eg, headache medicine, etc.). In addition, it is also used as a baking powder in making cake Sodium bicarbonate with common names in life is baking soda is used to make food cracky, porous.

In the presence of H + ions and sodium bicarbonate, CO2 is produced. Apperance: Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine hygroscopic powder.
