Sodium Sulfide

 

Na2S, a salt; colorless crystals. Density, 1.856 g/cm3; melting point, 1180°C. It is extremely hygroscopic. Solubility in water, 13.6 percent at 20°C and 45.0 percent at 97.5°C. It forms crystal hydrates. Aqueous solutions of Na2S are alkaline. Sodium sulfide is prepared by reduction of Na2SO4 and is used in the manufacture of sulfide dyes, in the textile and leather industries, and in ore flotation. Sodium hydrosulfide, NaHS, is used in the manufacture of rayon and in the leather industry.
