In a chemical reaction, substance A transfers electrons to substance B. Which statement is correct?
1. Substance B is oxidized and acts as the reducing agent.
2. Substance B is reduced and acts as the oxidizing agent.
3. Substance A is oxidized and acts as the oxidizing agent.
4. Substance A is reduced and acts as the reducing agent.
To determine the correct statement in this chemical reaction scenario, we need to understand the definitions of oxidation and reduction, as well as the roles of reducing and oxidizing agents.
Oxidation involves the loss of electrons, while reduction involves the gain of electrons.
The substance that is oxidized is the one that loses electrons, while the substance that is reduced is the one that gains electrons.
The reducing agent is the substance that donates electrons and causes another substance to be reduced. The reducing agent itself undergoes oxidation.
The oxidizing agent is the substance that accepts electrons and causes another substance to be oxidized. The oxidizing agent itself undergoes reduction.
Now, in the given scenario, substance A transfers electrons to substance B. This means substance A is losing electrons and substance B is gaining electrons.
From this information, we can conclude that substance A is being oxidized (loses electrons) and substance B is being reduced (gains electrons).
So, the correct statement would be:
4. Substance A is reduced and acts as the reducing agent.
The correct statement is:
1. Substance B is oxidized and acts as the reducing agent.
The correct statement is:
1. Substance B is oxidized and acts as the reducing agent.
