Potassium hydroxide (KOH) is a strong alkaline compound commonly known as caustic potash. It appears as a white, solid substance and is highly soluble in water, producing a strongly basic solution. KOH is widely used in various industries, including manufacturing soaps, fertilizers, and cleaning agents. In addition to its industrial applications, potassium hydroxide plays a role in laboratories for pH regulation and as a reagent in chemical reactions. It can also be used in food processing, particularly in the production of certain types of olives and as a food additive to regulate acidity.
