| | Sodium sulfide Usage And Synthesis |
| Chemical Properties | crystals of varied colour, with a repulsive odour | | Usage | used in sulfur dyes, used as reductant, mordant, floatation agent, depilatory for leather, digestion auxiliary in paper-making, and used in textile, pigment and rubber | | General Description | Sodium sulfide is a yellow to brick red crystalline mass or fused solid with an odor of rotten eggs. If exposed to moist air Sodium sulfide is liable to spontaneous heating and may cause ignition of nearby combustible material. Sodium sulfide absorbs moisture from the air. | | Air & Water Reactions | Aqueous solutions of sodium sulfide when exposed to air slowly convert to sodium hydroxide and sodium thiosulfate. The crystalline form upon exposure to air forms hydrogen sulfide and sodium carbonate [Merck 11th ed. 1989]. | | Reactivity Profile | SODIUM SULFIDE is a white to yellow crystalline material, flammable. Can explode on rapid heating or when shocked. Violent reaction with carbon, charcoal, diazonium salts, N,N-dichloromethylamine, strong oxidizers, water. On contact with acids Sodium sulfide liberates highly toxic and flammable hydrogen sulfide gas. When heated to decomposition Sodium sulfide emits toxic fumes of sodium oxide, and oxides of sulfur [Bretherick, 5th ed., 1995, p. 1729]. | | Health Hazard | Caustic action on skin and eyes. If ingested may liberate hydrogen sulfide in stomach. | | Fire Hazard | Special Hazards of Combustion Products: Irritating sulfur dioxide is produced in fire. |
