General Description

Dihydrogen selenide, also known as hydrogen selenide, is a chemical compound with the formula H2Se. It is a colorless, highly toxic gas with a characteristic foul odor similar to that of rotten eggs. Dihydrogen selenide is a weak acid and can react with strong bases to form selenide salts. It is also flammable and easily forms explosive mixtures with air. Exposure to dihydrogen selenide can cause irritation to the eyes, skin, and respiratory system, as well as more severe health effects such as pulmonary edema and liver and kidney damage. Due to its toxicity and hazardous properties, dihydrogen selenide is handled and used with extreme caution in industrial and laboratory settings.
