Chemistry - Hydrogen and Its compound Question with Solution | TestHub

Question Explanation:

Determine final oxidation state of oxygen in a reaction.

Concept: Redox reactions of hydrogen peroxide.

Solution:  

In the reaction, ${\mathrm{ClO}}_3^{-}$ is a strong oxidizing agent, and H₂O₂ acts as a reducing agent.

When H₂O₂ acts as a reducing agent, the oxidation state of its oxygen atoms increases from –1 to 0 , producing elemental oxygen (O₂).
