What is a Hydroselenic acid (H₂Se)?

Hydroselenic acid (H₂Se) is a chemical compound consisting of selenium and hydrogen. It is a colorless gas with a strong odor similar to hydrogen sulfide. Hydroselenic acid is highly toxic, and inhalation can cause acute poisoning symptoms. When dissolved in water, it forms an acidic solution and exhibits strong corrosive properties, requiring careful handling. Industrially, hydroselenic acid can be produced during the manufacture of selenium-containing compounds, particularly in the production of selenium-based fertilizers and pesticides. It is also used in the semiconductor industry. Due to its toxicity, it requires stringent safety precautions, including protective equipment and adequate ventilation. Prolonged exposure can adversely affect the respiratory and nervous systems, making proper safety management crucial.
