Potassium Hydroxide, often referred to as caustic potash, is a strong alkaline compound with the chemical formula KOH. It appears as a white, solid substance and is highly soluble in water, producing a strongly basic solution. This compound is commonly used in various applications, including the production of biodiesel, soaps, and fertilizers. In addition to its industrial uses, Potassium Hydroxide is also utilized in laboratories for pH regulation and as a reagent in chemical reactions. Due to its caustic nature, it can cause burns and should be handled with care, using appropriate safety equipment.
