In a chemical reaction where substance A transfers electrons to substance B, the correct statement is:
Substance A is oxidized and acts as the oxidizing agent.
Here's the reasoning:
- When substance A transfers electrons, it loses electrons, which means it is being oxidized.
- Substance B, receiving the electrons, is being reduced (gaining electrons).
- An oxidizing agent is the substance that gets reduced while causing another substance (in this case, substance A) to oxidize.
Thus, the statement "Substance A is oxidized and acts as the oxidizing agent" is correct.
