Answer:
Ca, Zn, Ni, Al, Fe
Explanation:
The activity series is an arrangement of metals in order of decreasing reactivity.
Metals that are high up in the activity series are very reactive. They displace metals that are lower in the activity series from an aqueous solution of their salts.
The metals; Ca, Zn, Ni, Al, Fe are all above Pb in the activity series hence they will cause Pb2+ ions to come out of solution as solid Pb.
A more reactive metal displaces the less reactive metals in the solution. Ca, Al, Zn, and Fe can be accomplished to take out the [tex]\bold{ Pb^2^+}[/tex] from the solution as solid Pb.
Metal displacement Reaction:
In this type of reaction a more reactive metal displaces the less reactive metals in the solution.
The metal reactivity series
Ca > Al > Zn > Fe > Ni > Pb > Ag > Au
The lead ( Pb) is less reactive than the Ca, Al, Zn, and Fe.
Therefore, Ca, Al, Zn, and Fe can be accomplished to take out the [tex]\bold{ Pb^2^+}[/tex] from the solution as solid Pb.
