Sodium Bicarbonate, also known as Sodium Bicarbonate, is a inorganic compound Sodium Bicarbonate. It has a chemical formula of NAHCO3, a small white crystal that is less soluble in water than Sodium carbonate. White powder crystal, or opaque monoclinic system of fine crystals, odorless, salty taste, soluble in water, insoluble in ethanol. The solubility in water is 7.8 g (18 ° C) and 16.0 G (60 ° C) . The Sodium bicarbonate is an acid salt formed by neutralization of a strong base with a weak acid. When dissolved in water, it is weakly alkaline. This property enables it to be used as a bulking agent in food production. 

The chemical property is stable at room temperature and decomposes easily when heated. It decomposes rapidly above 50 â ° C and loses carbon dioxide completely at 270 â ° C. it does not change in dry air and decomposes slowly in moist air. Can react with both acid and alkali. It reacts with acid to form corresponding salt, water and carbon dioxide, and with alkali to form corresponding carbonate and water. In addition, it can react with certain salts and double hydrolyze with aluminum chloride and aluminum chlorate to form Aluminum hydroxide and sodium salts as well as carbon dioxide.

The pharmaceutical industry: Sodium bicarbonate can be used directly as a raw material for the pharmaceutical industry to treat acid reflux.

        Use of baking soda 2. Food processing in the food industry, Sodium bicarbonate is widely used as a puffing agent, especially in the production of biscuits and bread. However, sodium carbonate may be left behind after use, and overuse may increase the alkalinity of foods, thereby impairing flavor and turning them a yellowish-brown color. In addition, it is a key ingredient in carbonated beverages that produces carbon dioxide. The Sodium bicarbonate can also be combined with alum to make alkaline baking powder, or with soda ash to make civil soda ash. It also acts as a preservative for butter. When handling vegetables, Sodium bicarbonate can be used as a colour fixative for fruits and vegetables. About 0.1% to 0.2% Sodium bicarbonate is added during the washing process to help maintain the green stability. As a fruit and vegetable treatment agent, Sodium bicarbonate can increase the pH of fruits and vegetables by boiling and bleaching, enhance the water holding capacity of protein, promote the softening of food tissue cells, and help the dissolution of astringent ingredients. In addition, Sodium bicarbonate has the effect of deodorizing goat milk, the recommended dosage is 0.001% to 0.002% .

Use of baking soda 3. Fire-fighting equipment is used to produce acid-base extinguishers and foam extinguishers.
