Sodium Bicarbonate Baking Soda Food Grade Wide Range Usage White Powder
Sodium bicarbonate (NaHCO₃), commonly known as baking soda, is a white solid that is soluble in water and decomposes slowly in moist air. It is a white fine crystal and its solubility in water is less than that of sodium carbonate. White powder-like crystals, or opaque monoclinic fine crystals, odorless, salty in taste, soluble in water, insoluble in ethanol. Its solubility in water is less than that of sodium carbonate and it is weakly alkaline.

Baking soda has extensive applications in industry:
1. Food processing industry
Leavening agent: sodium bicarbonate, in baked goods such as bread, cakes and biscuits, reacts with acidic substances to produce carbon dioxide gas, causing the dough to expand and become soft, and enhancing the texture.
pH regulator: It is used to adjust the pH level of food to ensure its stability and safety. In beverage production, baking soda is also used to adjust the taste, providing a unique flavor and effervescence for some carbonated drinks.
2. Pharmaceutical industry
Buffer: In the pharmaceutical process, sodium bicarbonate is often used as a buffer to help regulate the pH value of the drug and ensure its stability and effectiveness in the human body.
Antacids: Baking soda can also be used as an antacid, directly to treat stomach discomfort caused by excessive stomach acid, such as stomach pain and heartburn.
3. Textile and leather Iindustry
Fiber pretreatment: In the textile industry, sodium bicarbonate can be used for the pretreatment of fibers to remove impurities and oil stains and improve the dyeing performance of fibers.
Dyeing adjustment: During the dyeing process, sodium bicarbonate can adjust the pH value of the dyeing solution to ensure uniform and bright dyeing.
4. Leather processing: For leather products, sodium bicarbonate is used in the tanning and cleaning processes to help the leather achieve the desired softness and luster, while removing odors and residues.
Environmental protection and cleaning industries:
Wastewater treatment: Baking soda can be used to adjust the pH value of wastewater, promoting the precipitation and removal of heavy metal ions, thereby purifying the water quality.
As a green and environmentally friendly cleaner, baking soda can effectively remove oil stains, scale and odors without causing pollution to the environment.
Air purification: Baking soda can also serve as an air purifier, adsorbing and removing harmful gases and odors in the air, providing fresh air for the indoor environment.
5. Petrochemical industry
Desulfurizer: In the petrochemical industry, sodium bicarbonate can be used as a desulfurizer in the petroleum refining process to remove sulfides from petroleum and improve the quality and environmental performance of petroleum products.
Reactants and catalysts: In the process of chemical synthesis, baking soda is also frequently used as a reactant or catalyst, participating in various chemical reactions to produce a wide range of chemicals and materials.
6. Agriculture and Animal Husbandry
Soil improvement: In agriculture, sodium bicarbonate can be used for soil improvement, regulating soil pH, enhancing soil fertility, and promoting crop growth.
Feed additive: In animal husbandry, sodium bicarbonate, as a feed additive, can supplement the reduction of carbonate in the blood of poultry caused by hot wheezing and improve the calcium metabolism of the body. Meanwhile, it can enhance the mobility of phosphorus in egg-laying poultry and maintain the concentration of phosphorus in their blood at the optimal level necessary for eggshell formation. In addition, it can also provide a sodium source to keep the blood at an appropriate sodium concentration.
7. Fire protection industry
Sodium bicarbonate is an important raw material for the production of acid and alkali fire extinguishers and foam fire extinguishers. As one of the main components of dry powder fire extinguishing agents, it can quickly absorb heat and lower the temperature of the burning material, while reacting with the active groups on the surface of the burning material to inhibit the progress of the combustion chain reaction, thereby achieving the purpose of fire extinguishing.
