consumption of IrCl612*" in the presence of oxygen probably occurs because sulfur(V) intermediates are scavenged by oxygen instead of by IrCl62". The absence of strong catalysis by copper(II) suggests that sulfur(V) intermediates react very rapidly with IrCle2-, however. The lack of rate dependence on buffer concentration confirms that the [H+] dependence shown in eq II should not be replaced by acetate or acetic acid dependences.The fact that the data do not show much evidence that a term second order in HS03~s hould be added to eq II shows that reduction by S2O52" is not an important reaction under
