Verified step by step guidance1
Understand the concept of a redox reaction: A redox reaction involves the transfer of electrons between two species. It consists of two half-reactions: oxidation (loss of electrons) and reduction (gain of electrons).
Identify the role of the oxidizing agent: In a redox reaction, the oxidizing agent is the species that gains electrons and is reduced. It causes another species to be oxidized.
Differentiate between oxidizing and reducing agents: The reducing agent is the species that loses electrons and is oxidized. It causes another species to be reduced.
Consider the options given: Oxidizing agent, Reducing agent, Inert gas, Catalyst. Determine which of these is typically reduced in a redox reaction.
Conclude that the oxidizing agent is the species that is reduced during a redox reaction, as it gains electrons.
