The Rate of Oxidation Reaction of Nitrite in an Alkaline Permanganate Solution

Abstract

The oxidation of nitrite by manganate and permanganate was investigated in 10. v2 mpl/l petassium hydroxide solution at 20. v80C. Permanganate oxidizes nitrite to nitrate by thc following equation.
NO2- +2MnO- +20H -. NQsin L+ 2 MnOs2in + H20
The rate of oxidation in 10 1 mo1/l potassium hydroxide is shown as follows.
d(NO2bdt) exp( 95, , (N, 2))
Our experiments reveal that nitrite is not oxidized, with manganate in an alkaline solution.
