Sodium bicarbonate has been used in many fields with its unique chemical properties. In food, it is a baking leavening agent, which produces carbon dioxide when heated to make cakes fluffy; in medicine, it can neutralize stomach acid, adjust acid-base balance, and treat excessive stomach acid; in the chemical industry, it is a raw material for fire extinguishers, and decomposition can quickly extinguish fires; in agriculture, it can adjust soil pH and prevent and treat fruit and vegetable diseases; in daily cleaning, weak alkalinity can remove dirt and odors. From kitchens to factories, from medical care to agriculture, it is fully embedded in production and life, and can be called an "all-round chemical player", relying on "one material with multiple functions" to release value in various scenarios.
