Question

6. CuO+ H2→ Cu + H2O
6. Which of the following pair is correct regarding to oxidation and reduction?

Answer 1

Answer:

Option B

Explanation:

Since after the reaction, the Oxygen molecule of CuO gets removed. So it is reduced.

Whereas after the reaction, Hydrogen gains an Oxygen molecule. So it is oxidized.

Hope this helps you :)

Answer 2

CuO undergoes reduction and Hydrogen undergoes oxidation.

• When a species removes its electron it is called oxidation and when a species accepts an electron called reduction.
• The reaction is-
• $CuO+H_2\rightarrow Cu+H_2O$
• Here oxidation state of Cu in CuO is +2. So, it converted to Cu and undergoes reduction.
• The oxidation state of Hydrogen is 0. It is converted to water and undergoes oxidation.
