Abstract
Redn. of Fe(III) to Fe(II) is obsd. in the reaction of [Fe(H2O)6]3+ with pyrazoic acid. When an excess of Fe is present, the reaction involves a transfer of four electrons per mol of acid. At room temp. the redox reaction, which is dependent on H+, Fe3+, and pyrazoic acid concns., is rather slow and is the rate-detg. step. The kinetic study was carried out at 50.0 ± 0.1°. The redox reaction is followed by a fast reaction of the Fe2+ with an excess of ligand, resulting in the prodn. of well-known complexes, where the acid acts as a chelating ligand through the N and O atomsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
