The kinetics and mechanism of the oxalic acid catalysed oxidation of nitrous acid by vanadiem(V) have been studied in 1 M perchloric acid medium. The reaction is first order each in vanadium(V) and nitrite and fractional order in oxalic acid. Nitrate ion retards the rate of the reaction. At low [H+] (0.5 —1.2 M) the rate of the reaction is independent of [H+] but at higher concentrations, the rate decreases. Kinetic as well as apectroabotometric evidence for the formation of a 1 : 1 complex between vanadium(V) and oxalic acid has been obtained and a mechanism involing this complex has been proposed.
