Sodium Sulphide Flakes

Product Description
Sodium Sulphide Flakes (Na₂S) are bright yellow to orange crystalline flakes widely used as a strong reducing agent, sulfur source, and chemical intermediate. Known for their high solubility in water and strong alkalinity, they are essential in industrial processes such as leather tanning, textile processing, and chemical manufacturing. In laboratories, Sodium Sulphide is used for precipitation reactions, sulfide ion generation, and analytical chemistry applications.
