| hydrogen sulfide |
Hydrogen Sulfide is a colorless, very flammable gas. In low concentrations it smells like "rotten eggs" however the sense of smell is lost after 2-15 minutes of exposure making it impossible to smell dangerous concentrations. It is heavier than air. It is considered to be a very toxic gas. When H 2 S burns it produces another very toxic gas - Sulfur Dioxide (SO 2 ). H 2 S is used in metallurgy, the preparation of phosphorous and oil additives, as well as a reagent in chemical analysis. ...
