In which situation is a substance oxidised?
Answer and explanation
Correct answer: Oxygen is added to it
Oxidation is a process in which oxygen is added to a substance or hydrogen is removed from it. Therefore, a substance is oxidised when oxygen is added to it. In contrast, addition of hydrogen or removal of oxygen is reduction; a decrease in temperature alone does not indicate oxidation.
