Oxidizing agents are defined as materials that do what when combined with oxygen?

• A. Increase the positive charge by removing electrons
• B. Decrease the oxidation state
• C. Become inert
• D. Always form acids upon reaction

Answer: (A)

Oxidizing agents enable oxidation to occur by taking electrons from another substance. In redox terms, the oxidizing agent is the species that gets reduced because it accepts those electrons. So, when an oxidizing agent interacts with another substance, it gains electrons and its oxidation state decreases. Describing the oxidizing agent as “increasing the positive charge by removing electrons” would mean it is losing electrons and becoming more positively charged, which is the opposite of what happens to an oxidizing agent. That behavior is characteristic of a substance that is being oxidized (or acts as a reducing agent in the other half-reaction), not of an oxidizing agent.
