⚠️ For information only; not a substitute for the official Safety Data Sheet (SDS).
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.
