Hydrogen sulfide (sulfurous hydrogen, hydrogen sulfide, dihydrosulfide).
Colorless gas with sweetish taste producing a characteristics unpleasant heavy odor of rotten eggs (rotten meat). Highly flammable gas. It may form a flammable mixture with air. May react intensely with oxidants.
- Colorless gas with a sweetish taste
