Widely used in titration processes to determine the concentration of acids in various samples, ensuring precise measurements in analytical chemistry. Essential in the manufacturing of soaps and detergents, where it acts as a key ingredient in saponification reactions. Utilized in the paper and pulp industry to break down lignin, facilitating the separation of cellulose fibers. Plays a critical role in water treatment processes, effectively neutralizing acidic components and adjusting pH levels. Also employed in the food industry for cleaning and sanitizing equipment, as well as in the production of certain food products like pretzels for surface treatment.
