In the scenario you described where substance A transfers electrons to substance B, we can analyze the process in terms of oxidation and reduction.
- Substance A is losing electrons; this means it is being oxidized.
- Since A is being oxidized, it is acting as the reducing agent (the substance that donates electrons).
- Substance B is gaining electrons, which means it is being reduced.
- Since B is being reduced, it acts as the oxidizing agent (the substance that accepts electrons).
Given this information, the correct statements are:
- Substance A is oxidized and acts as the reducing agent.
- Substance B is reduced and acts as the oxidizing agent.
If you have to choose just one statement from your options, the correct one is:
Substance A is oxidized and acts as the reducing agent.
