Sodium bicarbonate, with a chemical formula of NaHCO3, is an inorganic compound commonly known as baking soda, baking powder, baking alkali, etc. For white fine crystals, its solubility in water is less than that of sodium carbonate, which is weakly alkaline. Sodium bicarbonate is soluble in water and the solution is alkaline. It decomposes when heated in the air and releases carbon dioxide.
Sodium bicarbonate can react with acids to produce corresponding salts and water, and is an important neutralizer. It is relatively stable in a dry environment, but it absorbs moisture.

1. Pharmaceutical Industry:
Sodium bicarbonate can be directly used as a raw material in the pharmaceutical industry to treat excessive stomach acid.
2. Food Processing:
In the food manufacturing industry, sodium bicarbonate is widely used as a leavening agent, especially in the production of biscuits and bread. However, sodium carbonate may be left behind after use, and excessive use may increase the alkalinity of the food, which damages the flavor and turns its color to yellowish brown. In addition, it is a key component in the production of carbon dioxide in carbonated beverages. Sodium bicarbonate can also be combined with alum to make alkaline baking powder, or combined with soda ash to make domestic stone alkali. It also acts as a preservative for butter.
When treating vegetables, sodium bicarbonate can be used as a color protectant for fruits and vegetables. In the process of washing fruits and vegetables, adding about 0.1% to 0.2% sodium bicarbonate can help maintain the stability of green. As a fruit and vegetable treatment agent, sodium bicarbonate can increase the pH value of fruits and vegetables by boiling and bleaching, enhance the water retention capacity of proteins, promote the softening of food tissue cells, and help the dissolution of astringent ingredients. In addition, sodium bicarbonate has a mutton effect on goat milk, and the recommended amount is 0.001% to 0.002%.
3. Fire Equipment:
For the production of acid and alkali fire extinguisher and foam fire extinguisher.
4. Others:
Rubber industry can be used for rubber and sponge production; It can be used as a flux for casting ingot in the metallurgical industry; In the machinery industry can be used as casting steel (foundry) sand molding AIDS; In the printing and dyeing industry, it can be used as fixing agent for dyeing and printing, acid-alkali buffer, and rear treatment agent for fabric dyeing and finishing. Adding baking soda to dyeing can prevent the yarn from producing colored flowers; The pharmaceutical industry is used as raw material for making acid; It can also be used as a detergent for wool and for agricultural soaking.
