Potassium sulfide (Cat No.: M046688) is an inorganic compound composed of potassium cations and sulfide anions, typically appearing as a yellow to colorless crystalline solid. It is highly hygroscopic and reacts readily with water to produce potassium hydroxide (KOH) and hydrogen sulfide (H₂S) gas, which is toxic and has a characteristic rotten egg smell. Potassium sulfide is used in inorganic synthesis, analytical chemistry, and pyrotechnics, and can act as a sulfur source or reducing agent in various industrial and laboratory applications.
