In a redox reaction, which substance acquires electrons?

In a redox reaction, the substance that acquires electrons is identified as the reducing agent. This is because the reducing agent undergoes oxidation by losing electrons, while simultaneously, it facilitates the reduction of another substance by providing those electrons. In essence, while the reducing agent donates electrons, the substance being reduced accepts those electrons.

Understanding this relationship is crucial in redox chemistry, as it highlights the interplay between oxidation and reduction processes. The reducing agent is instrumental in enabling the reduction half of the reaction, showcasing its vital role in transferring electrons to the oxidizing agent, which is the substance being reduced. This transfer is fundamental to the chemical reaction taking place.
