Most often, the O element in a molecule of a substance: a) an oxidizing agent b) a reducing agent c) an oxidizing agent and reduction
Answer: b) a reducing agent.
Explanation of the solution to the problem: an oxygen atom in a molecule of a substance is only a reducing agent, because an oxygen atom in this case during redox reactions can only donate electrons, thereby increasing its oxidation state (to 0), thus forming a simple oxygen molecule.
In complex substances, oxygen is mainly in the minimum oxidation state, so it cannot be an oxidizing agent (because it can no longer accept electrons).
