Sodium. In addition to baking soda, there are baking soda, fermented soda and heavy alkali.
Baking soda is a white crystal, easily soluble in water, and its aqueous solution is weakly alkaline. In hot air, it can slowly decompose and release a part of carbon dioxide; When heated to 270℃, carbon dioxide is completely decomposed and released.
2 nahco3 = = = Na2CO3+H2O+CO2 writes that it can also react with acids (such as hydrochloric acid) to release carbon dioxide:
Sodium bicarbonate+hydrochloric acid = = = sodium chloride +H2O+ carbon dioxide
These characteristics of baking soda make it have many important uses in production and life. In fire extinguishers, it is one of the raw materials to produce carbon dioxide; In the food industry, it is the main raw material of baking powder; It is also a common raw material for making cold drinks; Medically, it is a medicine for treating hyperacidity.
