Organic chemistry. Nitrous acid is used to prepare diazonium salts: HNO 2 + ArNH 2 + H + → ArN + 2 + 2 H 2 O. where Ar is an aryl group. Such salts are widely used in organic synthesis, e.g., for the Sandmeyer reaction and in the preparation azo dyes, brightly colored compounds that are the basis of a … Meer weergeven Nitrous acid (molecular formula HNO 2) is a weak and monoprotic acid known only in solution, in the gas phase and in the form of nitrite (NO 2) salts. Nitrous acid is used to make diazonium salts from amines. The resulting … Meer weergeven Nitrous acid is usually generated by acidification of aqueous solutions of sodium nitrite with a mineral acid. The acidification is usually conducted at ice temperatures, and the HNO2 is consumed in situ. Free nitrous acid is unstable and decomposes rapidly. Meer weergeven Nitrous acid is involved in the ozone budget of the lower atmosphere, the troposphere. The heterogeneous reaction of nitric oxide (NO) and water produces nitrous acid. When this reaction takes place on the surface of atmospheric aerosols, the product readily Meer weergeven In the gas phase, the planar nitrous acid molecule can adopt both a syn and an anti form. The anti form predominates at room temperature, and IR measurements indicate it is more stable by around 2.3 kJ/mol. • … Meer weergeven Nitrous acid is the main chemphore in the Liebermann reagent, used to spot-test for alkaloids.
