Answer: oxidizing agent: [tex]Cu^{2+}[/tex], reducing agent :[tex]Zn[/tex]
Explanation: Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.
For the given reaction:
[tex]Zn(s)+Cu^{2+}(aq)\rightarrow Zn^{2+}(aq)+Cu(s)[/tex]
On reactant side:
Oxidation state of zinc = 0
Oxidation state of copper = +2
On product side:
Oxidation state of zinc = +2
Oxidation state of copper = 0
The oxidation state of copper reduces from +2 to 0, it is getting reduced. The substance which itself gets reduced, oxidizes other and is called as oxidizing agent.Thus [tex]Cu^{2+}[/tex] acts as oxidizing agent.
The oxidation state of zinc increases from 0 to +2. Thus, it is getting oxidized and it undergoes oxidation reaction. The substance which itself gets oxidized, reduces other and is called as reducing agent.Thus [tex]Zn[/tex] acts as reducing agent.
