Title: Reaction between hexacyanoferrate(III) ion and nitric and nitrous acids. Part I. Kinetics
Abstract: Hexacyanoferrate(III) ion, [Fe(CN)6]3–, reacts with 6 mol dm–3 nitric acid, in the presence of nitrous acid, to form an iron cyanonitrosyl complex according to the rate law v=k[Fe(CN)63–][HNO2]½. The reaction has been carried out in sulphuric acid, with low concentrations of nitric and nitrous acids, and k varies with h–½, an acidity function for ionisation of HNO3, and [HNO3]½. Reaction occurs by attack of an equilibrium concentrations of nitrogen dioxide on [Fe(CN)6]3– ion. The intermediate species so formed undergoes a further slow reaction, following first-order kinetics.
