In a chemical reaction, oxygen is removed from substance A and the same oxygen is added to substance B. What is the most appropriate classification of this reaction?
Answer and explanation
Correct answer: Redox reaction
Removal of oxygen from substance A is reduction, while addition of oxygen to substance B is oxidation. Because these two complementary processes occur simultaneously in one reaction, the overall reaction is classified as a redox reaction. Option B describes only oxidation and option C only reduction; neither represents the complete reaction. Neutralisation requires acid-base interaction.
