Sodium sulfide (CAT: R014560) is an inorganic compound typically available as colorless to yellowish solid flakes, pellets, or granules with a characteristic odor of hydrogen sulfide due to slight hydrolysis in moist air. It is highly soluble in water, producing strongly alkaline solutions, and is widely used in industrial applications such as leather processing, ore flotation, and pulp and paper manufacturing. In chemical synthesis, sodium sulfide serves as a reducing agent and a source of sulfide ions for producing sulfur-containing compounds, dyes, and polymers.
