preparation method | obtained by recrystallization of a precipitate formed by the interaction of a silver nitrate solution and nitrous acid in an aqueous solution at 70 °c. Sodium nitrite and silver nitrate reaction, the formation of pale yellow silver nitrite precipitation and sodium nitrate, the laboratory is also using this method to synthesize silver nitrite. |
Chemical reaction | the reaction of an alkyl halide with silver nitrite to form a mixture of a nitroalkane and a nitrite, called the Meyer reaction. Primary alkyl halides mainly produce nitroalkanes, secondary alkyl halides produce more nitrite, tertiary alkyl halides all produce nitrite. |
Use | used as reagent for calibration of potassium permanganate solution, determination of nitrite and identification of primary alcohol, secondary alcohol, tertiary alcohol. |
