| Hazard Information | Back Directory | 【General Description】
Ammonium sulfide aqueous solution is a colorless to yellow liquid, with an odor of rotten eggs or ammonia. Material in aqueous from the hydrosulfide which with acid forms H2S. AMMONIUM SULFIDE, SOLUTION(12135-76-1) may be irritating to skin, eyes and mucous membranes and may cause illness from skin absorption. AMMONIUM SULFIDE, SOLUTION(12135-76-1) may burn and/or emit toxic fumes if heated to high temperatures. | 【Reactivity Profile】
AMMONIUM SULFIDE SOLUTION is a strongly alkaline aqueous solution. Reacts with acids to generate toxic gaseous hydrogen sulfide. Reacts with bases to release gaseous ammonia. May react vigorously with oxidizing agents, including inorganic oxoacids, organic peroxides and epoxides. Special Hazards of Combustion Products: Toxic hydrogen sulfide gas is released when solution is heated. If ignited, this will form irritating sulfur dioxide gas [USCG, 1999]. | 【Air & Water Reactions】
Readily oxidized to be pyrophoric in air [Bretherick 1979 p. 120]. Ammonium sulfide is slowly decomposed by moisture giving off hydrogen sulfide, a flammable gas. Heat is generated when the pure compound is first dissolved in water. | 【Health Hazard】
Inhalation of 500 ppm for 30 min. produces headaches, dizziness, bronchial pneumonia; 600 ppm for 30 min. can cause death. Ingestion causes severe irritation of mucous membranes and stomach. Contact with liquid causes severe burns of eyes and severe skin irritation. May be absorbed through skin and cause hydrogen sulfide poisoning. | 【Fire Hazard】
Special Hazards of Combustion Products: Toxic hydrogen sulfide gas is released when solution is heated. If ignited, this will form irritating sulfur dioxide gas. |
