Answer: The correct answer is copper is getting reduced.
Explanation:
Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases. These reaction are shown by reducing agents.
[tex]X\rightarrow X^{n+}+ne^-[/tex]
Reduction reaction is defined as the reaction in which an atom gains electrons. Here, the oxidation state of the atom decreases. These reactions are shown by oxidizing agents.
[tex]X^{n+}+ne^-\rightarrow X[/tex]
For the given chemical reaction:
[tex]Cu^{2+}(aq.)+2e^-\rightarrow Cu(s)[/tex]
Here, copper atom is gaining 2 electrons to form copper metal. Thus, it is undergoing reduction reaction and is getting reduced.
