CHEMICAL AND PHYSICAL PROPERTIES

Physical Description Ammonium sulfide aqueous solution is a colorless to yellow liquid, with an odor of rotten eggs or ammonia. Can slowly react with water to generate flammable and toxic hydrogen sulfide gas. This reaction is much faster with acid. It may be irritating to skin, eyes and mucous membranes and may cause illness from skin absorption. It may burn and/or emit toxic fumes if heated to high temperatures.
Color/Form Yellow-orange crystals.
Odor Strong odor of rotten eggs and ammonia
Boiling Point 104 °F at 760 mmHg (USCG, 1999)
Melting Point Approximately 0 °C; decomposes
Flash Point 72 °F (USCG, 1999)
Solubility Soluble in water
Density 0.99 to 1.01 at 68 °F (USCG, 1999)
Stability/Shelf Life True sulfide is stable only in absence of moisture & below 0 °C.
Decomposition At high temps decomposes into ammonium bisulfite, ammonia and polysulfides
Corrosivity Corrosive
Refractive Index Index of refraction: 1.467 at 20 °C/D /Ammonium sulfide solution/
Other Experimental Properties Forms crystals below -18 °C; at high temperatures it decomposes into NH4HS, NH3, polysulfides, etc
Chemical Classes Other Classes -> Sulfur Compounds
