sodium sulfide

[′sōd·ē·əm ′səl‚fīd]
(inorganic chemistry)
Na2S An irritating, water-soluble, yellow to red, deliquescent powder; melts at 1180°C; used as a chemical intermediate, solvent, photographic reagent, and analytical reagent. Also known as sodium sulfuret.

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.

I would like to have seen the comments section give a little more detail about the hazard of the chemical, for example, the greatest danger from calcium carbide is its reaction with water to produce acetylene which may explode or catch fire, dry ice can cause severe burns, and sodium sulfide produces hydrogen sulfide on contact with acid.
