Oxidation of Cu(I) by oxygen in concentrated NaCl solutions—I. Homogeneous kinetics of oxidation by molecular oxygen in solution

Abstract

The homogeneous oxidation of cuprous chloride in 2 M NaCl solutions by dissolved molecular oxygen was studied, using a batch reactor, at constant pH and temperature. The rate of homogeneous reaction is represented by the expression: ▪ where square brackets indicate concentrations, in the conditions: temperature 22°C and concentrations 0.0625 M for HCl and between 0.9 × 10 −3 M and 6.2 × 10 −3 M for Cu(I).
