Note. The mechanism of oxidation of hexacyanoferrate(II) by nitrous acid
Abstract
The kinetics of oxidation of [Fe(CN)6]3– by nitrous acid at 25 °C have been studied. Reaction is acid catalysed at low acidities, [H+]= 0.01 mol dm–3, but the rate is independent of acidity at [H+]= 0.5 mol dm–3. Reaction is encounter controlled and occurs between [HFe(CN)6]3– and [NO]+.
