03 · Handling and storage
Storing and handling Disodium sulfide
Reactivity
SODIUM SULFIDE is a white to yellow crystalline material dissolved in water, 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 it liberates highly toxic and flammable hydrogen sulfide gas. When heated to decomposition it emits toxic fumes of sodium oxide, and oxides of sulfur [Bretherick, 5th ed., 1995, p. 1729].
