which of the following substances in reduced in znO+c
Answers
Answer:
ZnO is reduced and act as oxidizing agent.
C is oxidized and act as reducing agent.
Explanation:
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 = +2
Oxidation state of carbon = 0
On product side:
Oxidation state of zinc = 0
Oxidation state of carbon = +2
The oxidation state of zinc reduces from +2 to 0, it is getting reduced. The substance which itself gets reduced, oxidizes other and is called as oxidizing agent.Thus ZnO acts as oxidizing agent.
The oxidation state of carbon 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 C acts as reducing agent.
