Potassium hydroxide is widely used in the manufacturing of soaps and detergents, where it acts as a strong base for saponification reactions. It is also employed in the production of biodiesel, where it serves as a catalyst in transesterification processes. In laboratory settings, potassium hydroxide is utilized in acid-base titrations and as a reagent in various chemical syntheses. Additionally, it finds applications in the food industry for pH regulation and in the production of potassium carbonate and other potassium compounds.
