Abstract:

The major result obtained is that in the reaction of plumbite with H2O2, all of the O in the PbO2 part of the solid is derived from the oxidizing agent. The PbII makes special use of the peroxide O, and keeps it distinct from other O with which it is in contact. Two rather different mechanisms remain for serious consideration. One is that a peroxide phase of formula PbIIO2 first precipitates, and then rearranges to PbO2. The other is that PbO2 is laid down directly from PbII and H2O2 as they come into contact on the solid. The essential difference is that by the first mechanism, PbII in being oxidized sees only peroxide oxygen, while by the second mechanism, it excludes other oxygen and selects peroxide oxygen in the act of being oxidized.
