1. Used as an analytical reagent, also used in inorganic synthesis and the pharmaceutical industry.
2. Used to treat acidemia. Antacids.
3. Used as a starter in the food industry, a generator of carbon dioxide in soft drinks and cold drinks, and a preservative for butter. It can be directly used as a raw material in the pharmaceutical industry. It can also be used for film production, leather tanning, mineral processing, smelting, metal heat treatment, fiber, rubber and agricultural seed soaking, etc. At the same time, it is also used as wool detergent, foam fire extinguishing agent, bath agent and so on.
4. Alkaline agent: leavening agent. It is often formulated with ammonium bicarbonate as a leavening agent for biscuits and cakes. The additional amount of wheat flour is 20g./kg. It can be used with citric acid, tartaric acid, etc. to prepare foaming agents for solid refreshing drinks (to produce CO2).
5. As an acidity regulator and chemical leavening agent, our country stipulates that it can be used for all kinds of foods that need to be added with leavening agent and should be used in appropriate amounts according to production needs.
6. Carbon-alkali balance medicine for injection. Used in food, medicine, motion picture film, leather tanning, mineral processing, metallurgy, fiber, rubber, and other industries. It can also be a detergent and fire extinguishing agent.
