Sodium Hydrogen Carbonate applications properties production
Sodium bicarbonate, commonly known as baking soda, is an important inorganic compound. Its English name is "Sodium Hydrogen Carbonate".
** Properties **: Sodium bicarbonate is a fine white crystal, and its solubility in water is less than that of sodium carbonate. It decomposes easily when heated to form sodium carbonate, carbon dioxide and water. It is stable in nature at room temperature, but reacts rapidly when exposed to acid to produce carbon dioxide gas.
** Production **: The production methods of sodium bicarbonate mainly include synthesis and natural alkali method. The synthesis method is made by chemical reaction using sodium chloride, ammonia, carbon dioxide and water as raw materials. First, ammonia gas is introduced into saturated salt water to form ammonia salt water, and then carbon dioxide is introduced to form sodium bicarbonate precipitation. After separation, washing and drying, the product is obtained. The law of trona is extracted from trona minerals, and sodium bicarbonate is obtained through a series of processing and refining.
** Application **: Sodium bicarbonate is widely used. In the food industry, it is a commonly used leavening agent. In the production of bread, cakes and other foods, sodium bicarbonate is added, which is decomposed by heat to produce carbon dioxide gas, forming a porous structure inside the food, thus making the food soft and delicious. In the field of medicine, sodium bicarbonate can be used to treat hyperacidity. Because it can neutralize with gastric acid (the main component is hydrochloric acid), relieve the discomfort caused by excessive gastric acid. In the field of fire protection, some types of fire extinguishers contain sodium bicarbonate. In case of fire, sodium bicarbonate decomposes to produce carbon dioxide, which plays a role in isolating the air from fire. In addition, in the chemical industry, printing and dyeing industries, sodium bicarbonate also has many applications, such as being used as a chemical raw material to produce other compounds, and in the printing and dyeing industry to adjust pH.
