In a chemical reaction, substance A transfers electrons to substance B. Which statement is correct?

Substance A is reduced and acts as the reducing agent. Substance A is reduced and acts as the reducing agent. Substance A is oxidized and acts as the oxidizing agent. Substance A is oxidized and acts as the oxidizing agent. Substance B is oxidized and acts as the reducing agent. Substance B is oxidized and acts as the reducing agent. Substance B is reduced and acts as the oxidizing agent. Substance B is reduced and acts as the oxidizing agent.

Substance A is oxidized and acts as the reducing agent. Substance B is reduced and acts as the oxidizing agent.

Substance A is oxidized and acts as the reducing agent.

In order to determine which statement is correct, let's first review the definitions of oxidation and reduction:

Oxidation: This is a chemical process in which a substance loses electrons, resulting in an increase in its oxidation state.

Reduction: This is a chemical process in which a substance gains electrons, resulting in a decrease in its oxidation state.

Now, in the given chemical reaction, substance A transfers electrons to substance B. Based on these definitions, we can deduce the following:

1. Substance A is losing electrons and, therefore, undergoing oxidation.
2. Substance B is gaining electrons and, therefore, undergoing reduction.

So, the correct statement is: Substance A is oxidized and acts as the reducing agent, while Substance B is reduced and acts as the oxidizing agent.

To summarize:
- In this reaction, Substance A is oxidized and acts as the reducing agent.
- In this reaction, Substance B is reduced and acts as the oxidizing agent.
