Question

A substance that brings about reduction or reduces another substance is called a reducing agent.

• A. True
• B. False

Answer 1

The correct option is A True

Red-ox reaction: The reaction in which both oxidation and reduction take place simultaneously is known as the red-ox reaction.

• Oxidising agent: A substance that brings about oxidation or oxidizes another substance is called an oxidizing agent.
• Examples- Oxygen$\left({\mathrm{O}}_2\right)$, Ozone$\left({\mathrm{O}}_3\right)$, Chlorine$\left(\mathrm{Cl}\right)$, Bromine$\left({\mathrm{Br}}_2\right)$, Potassium permanganate$\left({\mathrm{KMnO}}_4\right)$, Nitric acid$\left({\mathrm{HNO}}_3\right)$, Sulphuric acid$\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$, and Hydrogen peroxide$\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$, are oxidising agents.
• Reducing agent: A substance that brings about reduction or reduces another substance is called a reducing agent.
• Examples- Hydrogen$\left({\mathrm{H}}_2\right)$, Hydrogen sulphide$\left({\mathrm{H}}_2\mathrm{S}\right)$, Carbon$\left(\mathrm{C}\right)$, Sulphur dioxide$\left({\mathrm{SO}}_2\right)$, etc. are reducing agents.

The reaction between Copper oxide $\left(\mathrm{CuO}\right)$and Hydrogen$\left({\mathrm{H}}_2\right)$: Copper oxide reacts with Hydrogen to form Copper$\left(\mathrm{Cu}\right)$ and water$\left({\mathrm{H}}_2\mathrm{O}\right)$.
