Hydrogen sulfide (H2S) is a colorless and highly toxic acidic gas. It is an inorganic compound. It has no obvious smell at high concentrations, has a strong smell of rotten eggs at low concentrations, and has a sulfur smell at very low concentrations. In industrial applications, hydrogen sulfide is used in the flotation process of sulfide ores and is also an important raw material for the production of sulfur and sulfuric acid. Furthermore, in laboratories it is used as an analytical reagent, for example in the qualitative analysis of heavy metal ions.<\/p>\n
