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
.
