The combination that results in a redox reaction is:
Pb(s) and Fe(NO3)2(aq)
In this combination, lead (Pb) is a solid while iron(II) nitrate (Fe(NO3)2) is an aqueous solution. When Pb is added to Fe(NO3)2 solution, lead will oxidize to lead(II) ions (Pb2+), while iron(II) ions will be reduced to iron metal (Fe). This is a redox reaction where both oxidation and reduction occur.
