Sodium acetate is widely used as a buffering agent and pH regulator in chemical, pharmaceutical, food, and laboratory applications. It is used for preparing acetate buffer solutions, controlling acidity in biochemical experiments, manufacturing pharmaceuticals, textile processing, leather tanning, and as a catalyst or reagent in organic synthesis. In the food industry, it is used as an acidity regulator and preservative additive.
