Pb
Reason- In the reactant side the oxidation state of Pb was +2 in PbCl2 but after the reaction the oxidation state of Pb is 0 i.e. after the reaction PbCl2 is getting converted to Pb which is in 0 oxidation state. Therefore it means Pb has gained 2 electrons and got reduced from Pb(+2) to Pb(0). Gain of electrons is referred to as REDUCTION.
