Description
Sodium Sulfide (Na₂S) 60–70% is an industrial-grade, yellow or red-colored flake or lump chemical
used in a wide variety of industrial and chemical processes. It dissolves easily in water to form a strong alkaline solution
and releases hydrogen sulfide (H₂S) gas when exposed to acids. Produced through the high-temperature reduction of sodium sulfate with carbon,
Sodium Sulfide plays a critical role in the leather, textile, mining, pulp, and chemical industries.
