Question

Which of the following is an oxidizing agent?

(a) KMnO4

(b) NaOH

(c) CO

(d) All of the mentioned

I had been asked this question in examination.

My doubt is from Types of Oxidative Reactions topic in portion Oxidation of Unit Processes

Answer 1

The correct answer is:

(a) KMnO4

Potassium permanganate (KMnO4) is a strong oxidizing agent. It is commonly used in various chemical reactions to facilitate oxidation. KMnO4 has the ability to donate oxygen or accept electrons, thereby oxidizing other substances. It is often used in redox reactions, such as the oxidation of alcohols or the disinfection of water.

• NaOH (Sodium hydroxide) is a strong base, not an oxidizing agent.
• CO (Carbon monoxide) is a reducing agent, not an oxidizing agent.

Thus, KMnO4 is the only correct choice in this case.
