Question

Which one of the following statements is incorrect for the reaction CuO + H2 -----------> Cu + H2O

CuO is reduced
H₂ is oxidised
CuO is oxidising agent
H₂ is oxidising agent​

Answer 1

Answer:

"H2 is the oxidising agent" ------- is incorrect

Answer 2

The incorrect statement is: H₂ is oxidizing agent​.

About oxidizing agent:

• An oxidizing agent is one that gets reduced in a chemical reaction.
• It helps in the oxidation of another reactant.
• The oxidation state reduces during the reaction.

About reducing agent:

• A reducing agent is one that gets oxidized in a chemical reaction.

• It helps in the reduction of another reactant.
• Its oxidation state increases during the reaction.

In the given question,

The oxidation state of H₂  = 0

And it increases to +1 when H₂ converts to H₂O.

Hence, it is getting oxidized and thus is a reducing agent.
