An Au rotated ring-disk electrode (RRDE) was applied for the detection of soluble intermediate products during the anodic electrodeposition and cathodic dissolution of /beta/-PbO/sub 2/ in solutions of HClO/sub 4/. A soluble species which only can be reduced at the ring electrode is produced during the anodic nucleation and deposition processes for PbO/sub 2/(s) at the disk electrode. This soluble intermediate product is concluded to be Pb(IV) which is probably associated with oxygen, e.g., PbO/sup 2+/ or Pb(PH)/sub 2//sup 2+/. The cathodic ring current from detection of the soluble Pb(IV) species was studied as a function of the concentrations of Pb(II) and HClO/sub 4/, and variation of rotational velocity. The results are consistent with chronamperometric data for PbO/sub 2/(s) deposition described previously. Soluble Pb(IV) and Pb(III), as well as Pb(II), are concluded to be products of the cathodic dissolution of PbO/sub 2/(s).
