Sodium acetate finds diverse applications in the food industry, technology, and chemistry. In the food industry, it is used as an additive ($\text{E 262}$), primarily as an acidity regulator and preservative (e.g., in ketchup, bread, and preserved vegetables). In the textile industry, it is used for the neutralization of sulfuric acid waste. A particularly well-known technical application is its use in hand warmers, where it releases heat through an exothermic crystallization (heat-releasing process). In chemical analysis, it is used for the preparation of buffer solutions. Furthermore, it is employed as an odor neutralizer (e.g., in leather).
