In terms of oxygen, which correctly identifies oxidation and reduction?
Answer and explanation
Correct answer: Oxidation involves addition of oxygen and reduction involves removal of oxygen
Based on oxygen, oxidation is the addition of oxygen to a substance, whereas reduction is the removal of oxygen from a substance. For example, when copper gains oxygen, copper oxide forms; when oxygen is removed from copper oxide, copper is obtained. Therefore, option A is correct. Option B interchanges the definitions of oxidation and reduction.
