Question

Identify the reducing agent oxidizing agent in cuso4+zn

Answer 1

Answer:

Explanation:

Answer : The reducing agent and oxidizing agent are, zinc and copper respectively.

Explanation :

Oxidation-reduction reaction : It is a reaction in which oxidation and reduction reaction occur simultaneously.

Oxidation reaction : It is the reaction in which a substance looses its electrons. In this oxidation state increases.

Reduction reaction : It is the reaction in which a substance gains electrons. In this oxidation state decreases.

The balanced chemical reaction is,

Half reactions of oxidation and reduction are :

Reduction :

Oxidation :

From this reaction we conclude that the copper is reduced from (+2) to (0) oxidation state and zinc is oxidized from (0) to (+2) oxidation state. So, copper is an oxidizing agent and zinc is a reducing agent.

Hence, the reducing agent and oxidizing agent are, zinc and copper respectively.

Answer 2

Answer:

Oxidation number of Zn changes from 0 to +2, and the oxidation number of Cu goes from 2+ to 0. THis means, Zn is undergoing oxidation or being oxidized or acting as an reducing agent. Similarly, Cu2+ is undergoing reduction or being reduced or acting as an oxidizing agent.
