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^-}_I → ^k3 {Fe³⁺HO₂^-}_II {Fe ³⁺HO₂^-}_II + H₂O ₂ → ^k4 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.
