Potassium sulfide, represented by the formula K2S, is a compound with diverse industrial and research applications. Known for its polysulfide variants and hydrate forms, it plays a crucial role in various sectors due to its sulfide ion source properties.
It finds applications in pharmaceuticals, depilatories, analytical reagents, bath salts, copper plating, fertilizers, dyes, reducing agents, and skin disease treatments. Potassium sulfide is also vital in fireworks coloration, sulfur nanoparticle synthesis, and as a component in high-energy-density batteries.
With a molecular weight of 110.262 and a melting point of 840°C, potassium sulfide appears as a white crystalline solid that may turn red or brown upon moisture absorption. It is characterized by its odor, solubility in water, alcohol, and glycerin, and its pyrophoric and deliquescent nature.
Available both as a reagent for research in small quantities and as an industrial chemical, including in liquid form for dye applications, potassium sulfide caters to a wide range of industrial needs.
Produced in the lab by reacting potassium with sulfur in liquid ammonia or industrially by reacting potassium sulfate with carbon, potassium sulfide's production methods are as varied as its applications.
Known for its alkalinity, reducing, and corrosive properties, potassium sulfide reacts with air, water, acids, and oxidizing agents to produce a range of compounds, including toxic gases.
Potassium sulfide's pentahydrate form can be synthesized through specific reactions, demonstrating the compound's versatile chemical behavior.
Its pyrophoric nature poses risks of respiratory issues, skin irritation, and eye damage, necessitating strict protective measures during handling.
