Abstract

The decomposition of H2O2 by ferric perchlorate was investigated using parallel titrimetric and spectrophotometric measurements. During the decomposition complexes are formed between HO2- and Fe3+. The results can be represented by the following mechanism, involving two complexes: Fe3+ + HO2-k2 k1 {Fe3+HO2-} I {Fe3+HO2-}Ik3 {Fe3+HO2-}II {Fe 3+HO2-}II + H2O 2k4 products. The products are Fe3+, OH-, H2O and O2. At high [H2O 2]/[Fe3+] ratios (300 to 10) the kinetic results are satisfactorily represented by a mechanism involving the first complex only. At lower ratios (4 to 0.2) the second complex too becomes kinetically important.
