Used in fertilizers to provide potassium, an essential nutrient for plant growth, improving crop yield and resistance to disease. Widely used in agriculture, especially for potassium-deficient soils. Employed in medicine as a dietary supplement and to treat low blood potassium (hypokalemia). Administered orally or intravenously under medical supervision. Serves as a salt substitute in food for people reducing sodium intake, helping manage blood pressure. Used in industrial processes such as water treatment, metal processing, and in the production of other potassium compounds. Commonly used in laboratories for buffer solutions and in electrochemistry due to its high solubility and ionic conductivity.
