Answer: oxidizing agent: , reducing agent :
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:
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 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 acts as reducing agent.
