Microdetermination of nitrous acid was successfully established by introducing into the azotometry, the nitrogen gas generation by the reaction of nitrous acid and ammonium sulfaminate. The value of purity determination of potassium nitrite by this method agreed well with the result of potassium permanganate titration. Optimal determination range: 20-200 γ of nitrous acid.
