Hydrogen Selenide is an inorganic compound with the formula of H2Se. It’s the simplest ( and virtually the only) hydride of selenium. H2Se is a colorless, flammable gas under standard conditions. It is the most toxic selenium compound] with an exposure limit of 0.05 ppm over an 8-hour period. Even at extremely low concentrations, this compound has a very irritating smell resembling that of decayed horseradish or 'leaking gas,' but smells of rotten eggs at higher concentrations.
Hydrogen selenide is also dangerous to the environment. Hydrogen selenide is hazardous, being the most toxic selenium compound and far more toxic than its congener hydrogen sulfide.. The gas acts as an irritant at concentrations higher than 0.3 ppm, which is the main warning sign of …show more content…
exposure; below 1 ppm, this is "insufficient to prevent exposure", while at 1.5 ppm the irritation is "intolerable". Exposure at high concentrations, even for less than a minute, causes the gas to attack the eyes and mucous membranes (Hydrogen Selenide).
Hydrogen selenide, also known as hydroselenic acid, selenium hydride, or selanne, is a chemical compound.
Its chemical formula is H2Se. It is an acid that contains hydrogen and selenide ions. Hydrogen selenide is a colorless gas that dissolves in water to make an acidic solution. It smells like rotten horseradish and it is very toxic. It burns easily, making selenium dioxide. It is similar to hydrogen sulfide, a gas that smells like rotten eggs. It is a strong reducing agent. It can be used to add selenide ion to organic compounds. It can also be used to make selenium by reacting it with sulfur dioxide. This makes selenium, sulfur, and water
