N2 - The structure of the secondary iron(III)-hydrogen peroxide complex (C II) is investigated on the basis of a previously established ion-pair structure (Fe+3HO2-) for CI. Consideration of free radical mechanisms, following a hypothetical reduction of CI to CII, shows that such a reduction in the transition CI→CII is excluded. No transient change of pH is observed during the decomposition even under circumstances in which C II accumulates. This indicates that the acid equivalent, formed simultaneously with CI, disappears upon the formation of C II. The velocity constant of the transition is independent of pH. It is concluded, therefore, that the process consists of a loss of OH- ions. CII is identified as FeO3+.
