Na3As
Sodium arsenide, with the chemical formula Na3As, is an inorganic compound. It is an intermetallic compound formed between sodium and arsenic. Sodium arsenide is typically a crystalline solid. It is known to be a strong reducing agent. The compound is highly reactive and reacts vigorously with water, producing sodium hydroxide and arsine gas (AsH3), which is a highly toxic substance. Due to its reactivity and the toxicity of arsenic compounds, sodium arsenide is not commonly encountered outside of specialized laboratory settings or industrial processes. It is important to handle this compound with extreme caution due to the inherent dangers associated with arsenic.
