Ka of hydrazoic acid
Hydrazoic acid, also known as hydrogen azide or azoimide, is a compound with the chemical formula HN3. It is a colorless, volatile, and explosive liquid at room temperature and pressure. It is a compound of nitrogen and hydrogen, and is therefore a pnictogen hydride. It was first isolated in 1890 by … Visa mer The acid is usually formed by acidification of an azide salt like sodium azide. Normally solutions of sodium azide in water contain trace quantities of hydrazoic acid in equilibrium with the azide salt, but introduction of a … Visa mer In its properties hydrazoic acid shows some analogy to the halogen acids, since it forms poorly soluble (in water) lead, silver and mercury(I) salts. The metallic salts all crystallize in … Visa mer 2-Furonitrile, a pharmaceutical intermediate and potential artificial sweetening agent has been prepared in good yield by treating furfural with a mixture of hydrazoic acid (HN3) and perchloric acid (HClO4) in the presence of magnesium perchlorate in the Visa mer Hydrazoic acid reacts with nitrous acid: HN3 + HNO2 → N2O + N2 + H2O This reaction is unusual in that it involves compounds with nitrogen in four different oxidation states. Visa mer Hydrazoic acid is volatile and highly toxic. It has a pungent smell and its vapor can cause violent headaches.
