|nitrous acid |
A weak inorganic acid existing only in solution or in the form of its salts. It can act either as an oxidizing agent or as a reducing agent. Chemical formula: HNO2.
(HNO2), an unstable, weakly acidic compound that has been prepared only in the form of cold, dilute solutions. It is useful in chemistry in converting amines into diazonium compounds, which are used in making azo dyes. It is usually prepared by acidifying a solution of one of its salts, the nitrites, which are more stable (see nitrite).
