Early Stages

The reaction of cerium(1V) with peroxomonosulphuric acid in aqueous sulphuric acid has been shown to involve a short radical chain. Rates of reaction of cerium(1V) have been measured in dilute sulphuric acid solutions. A substantial difference was found between the apparent rate law in the early stages of reaction and that observed later. This is not due to the presence of hydrogen peroxide in the peroxomonosulphate solutions. A tentative mechanism is proposed.

Protonated Forms

The oxidation of the ethylenediphosphinetetraacetate anion and its protonated forms by iodine, periodate, hydrogen peroxide, and oxygen has been studied in aqueous solution. The oxidation by the first three reagents is fast and yields a single product, bis(phosphine oxide), which has been isolated and characterized as ethylenebis(phosphinyl)tetraacetic acid. The oxidation by molecular oxygen proceeds considerably more slowly; in weakly acid solutions its rate is determined by the properties of the oxygen rather than by the electronic structure of the various protonated substrate species. The inhibiting effect of the phosphonium structures takes place only in strongly acid solutions.
