Answer:
Displacement and redox reaction
Copper is displaced
Explanation:
Iron metal can react with a solution of a salt containing the copper (II) cation, for instance, copper (II) sulfate. This is a displacement reaction.
Fe(s) + CuSO₄(aq) → FeSO₄(aq) + Cu(s)
Fe is incorporated into the salt, forming iron (II) sulfate and Cu is displaced. This reaction can also be considered a redox reaction because iron is oxidized and copper is reduced.
