Question

in a chemical reaction, substance a transfers electrons to substance b. which statement is correct? (1 point)
substance a is reduced 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 a is oxidized and acts as the oxidizing agent.

Explanation:

Step1: Recall oxidation - reduction concepts

In a redox reaction, the substance that loses electrons is oxidized and acts as a reducing agent. The substance that gains electrons is reduced and acts as an oxidizing agent.

Step2: Analyze the electron transfer

Since substance A transfers electrons to substance B, substance A is oxidized (loses electrons) and acts as the reducing agent. Substance B is reduced (gains electrons) and acts as the oxidizing agent.

Answer:

Substance A is oxidized and acts as the reducing agent.
