Question

select the correct answer.
what happens to a reducing agent during a redox reaction?
a. the reducing agent is reduced.
b. the reducing agent is oxidized.
c. the reducing agent remains unchanged.
d. the reducing agent gains electrons.

Explanation:

A reducing agent in a redox reaction donates electrons. When it donates electrons, its oxidation state increases. Oxidation is the process of losing electrons (or increase in oxidation state). So, the reducing agent is oxidized.

Answer:

B. The reducing agent is oxidized.
