Abstract

The mechanism of decomposition of the aquo trivalent copper ions in neutral and acid solutions was investigated. The effect of NO₂^-, Br^-, CH₃OH, and H₂O₂ on the disappearance of Cu(III)(aq) was studied. It is concluded that in neutral solutions the trivalent copper exists in the form of CuOH²⁺(aq) or Cu(OH)₂⁺(aq) and decomposes via 2CuOH²⁺ → 2Cu²⁺ + H₂O₂. In acid solutions the mechanism involves the formation of hydroxyl radicals probably via Cu³⁺(aq) ⇄ Cu²⁺ + OH. The reaction Cu⁺ + CuOH²⁺(aq) is diffusion controlled.
