Potassium hydroxide solution is widely used in various industrial and chemical processes. It serves as a strong base in the production of soaps and detergents, where it saponifies fats and oils to create cleaning agents. In the food industry, it is employed as a pH regulator and for peeling fruits and vegetables. The solution is also utilized in the manufacturing of biodiesel, where it acts as a catalyst in the transesterification process. Additionally, it plays a crucial role in water treatment for neutralizing acidic waste and controlling pH levels. In laboratories, it is commonly used for chemical synthesis and as a reagent in analytical procedures. Its ability to absorb carbon dioxide makes it useful in gas purification systems.
