${\mathrm{Pb}}_3{\mathrm{O}}_4+8\mathrm{HCl}\to 3{\mathrm{PbCl}}_2+{\mathrm{Cl}}_2+4{\mathrm{H}}_2\mathrm{O}$.   Correct statement about this reaction is

1. It is a redox reaction

    ${\mathrm{PbO}}_2$ ---  Oxidant and base

    HCl – reductant and acid

Of the four moles of HCl only two moles undergo oxidation

2.It is an acid –base reaction but not a redox reaction

    PbO – Base

    HCl – Acid
