Abstract
Kinetics of oxidation of nitrite ion (NO2-) with Bi(V) fluoride complex hav e been investigated in HClO4-HF mixture. The reaction is first order in eac h reactant. Hydrogen ion (H+) and ionic strength have inverse effect on the reaction rate. The effect of HF and added fluoride ion (F-) are found to b e negligible. The mode of electron transference from the substrate (NO2-) t o the oxidant Bi(V) has been indicated via a bridged outer-sphere mechanism .
