Physical description & handling notes

  • Ammonium hydrosulfide, solution is a clear, yellowish liquid. Kept basic with NaOH, as acid will release hydrogen sulfide gas. Technical grade is 40-44%. Used in photography, textiles, synthetic flavors, coloring brasses, bronzes, and iron control.
  • White to yellow hygroscopic solid; [ICSC] Decomposes when moisture or >0 deg C; [Hawley] Technical grade is 40-44% and kept basic with sodium hydroxide; [CAMEO] Solution has strong odor of rotten eggs and ammonia; [CHRIS]
  • HYGROSCOPIC WHITE-TO-YELLOW CRYSTALS WITH CHARACTERISTIC ODOUR.
  • Solubility in water, g/100ml: 128.1
  • Vapor pressure, kPa at 22 °C: 52
  • room temperature. This produces toxic and corrosive gases including ammonia and hydrogen sulfide. Reacts with acids. This produces hydrogen sulfide and sulfur oxides. Reacts violently with oxidants. This generates fire or explosion hazard.
