Laboratory use
Sodium bicarbonate can be used as an analytical reagent and is also used in inorganic synthesis. Can be used to prepare sodium bicarbonate-sodium bicarbonate buffer solution, adding a small amount of acid or base can keep the hydrogen ion concentration does not change significantly, can keep the pH value of the system relatively stable.

Industrial use
Sodium bicarbonate can be used in the production of acid-base fire extinguishers and foam fire extinguishers, and sodium bicarbonate can be used in rubber and sponge production in the rubber industry. Sodium bicarbonate can be used as a flux for casting ingot in metallurgical industry. In the machinery industry, sodium bicarbonate can be used as a molding aid for casting steel (foundry) sand. In printing and dyeing industry, sodium bicarbonate can be used as fixing agent for dyeing and printing, acid-alkali buffer, and rear treatment agent for fabric dyeing and finishing. The addition of baking soda to dyeing can prevent the yarn from producing colored flowers, and can also be used as a detergent for wool.

Food processing use
In food processing, sodium bicarbonate is one of the most widely used loosening agents, used in the production of biscuits, bread, etc., but after the action will remain sodium carbonate, too much use will make the food alkalinity is too large and lead to bad flavor, yellow brown color. It is the producer of carbon dioxide in soft drinks; It can be combined with alum to form alkaline baking powder, and can also be combined with soda ash to form civil stone alkali. It can also be used as a butter preservative. In vegetable processing can be used as fruit and vegetable color protection agent. Adding about 0.1% to 0.2% sodium bicarbonate when washing fruits and vegetables can make the green stability. When sodium bicarbonate is used as fruit and vegetable treatment agent, the pH value of fruit and vegetable can be increased, the water retention of protein can be improved, the tissue cells of food can be softened, and the astringent components can be dissolved. In addition, it has the effect of removing the smell of sheep milk, and the use amount is 0.001% to 0.002%.

Agricultural and animal husbandry purposes
Sodium bicarbonate can be used for agricultural seed soaking, but also to make up for the lack of lysine content in feed, sodium bicarbonate dissolved in a small amount of water or mixed into concentrate to feed cattle (add the right amount), can promote the growth of cattle, but also significantly improve the milk production of cows.

Medical use
Sodium bicarbonate can be used as a pharmaceutical raw material for the treatment of excess stomach acid, metabolic acidosis, and can also alkalize urine to prevent uric acid kidney stones. It can also reduce the renal toxicity of sulfonamides, prevent hemoglobin deposition in renal tubules during acute hemolysis, and treat the symptoms caused by excessive stomach acid; Intravenous infusion has non-specific therapeutic effect on barbiturates, salicylic acids and methanol poisoning. However, it is prohibited for gastric lavage when swallowing strong acid poisoning, and a large number of injections, renal insufficiency or long-term application can cause arrhythmia, muscle spasm, pain, abnormal fatigue and weakness, slow breathing, oral odor, frequent urination, urgent urination, persistent headache, loss of appetite, nausea, vomiting, etc.
