Pb HO PbOHHO 23 2 22 ++()aq ++42()ls ()ga+ ()q Oxidizing Pb2+ deposits PbO 2 on the Pt anode. If we weigh the anode be-fore and after applying the potential, the change in its mass gives the mass of PbO 2 and, from the reaction's stoichiometry, the amount of Pb 2+ in the sample. This is a direct analysis because PbO 2 contains the analyte.
