Sodium Sulfide
CAS No.:
Factory price selling high-quality sodium sulfide
Detailed Description

Widely used in leather, paper, mineral processing, dye production, printing and dyeing, pharmaceutical, MSG, artificial fiber.


pure sodium sulfide is a colorless crystalline powder. Strong moisture absorption, soluble in water. Reaction was strongly alkaline aqueous solution. Contact with skin and hair will cause burns. Therefore, commonly known as sodium sulfide sodium sulfide. Sodium solution in the air will be slowly oxidized to sodium thiosulfate, sodium sulfite, sodium sulfate and sodium polysulfide. Since the formation of sodium thiosulfate faster, so the main product of oxidation is sodium thiosulfate. Deliquescent sodium sulfide in the air, and carbonation and deterioration, continued release hydrogen sulfide gas.

Industrial sodium sulfide due to impurities, the color pink, brown, khaki. Weight, melting point, boiling point, but also because of the effects of different impurities. When the sodium sulfide exposed to humid air when, Na2S and its hydrates emit hydrogen sulfide.
