When oxygen is added to a substance, what is the process called?

Answer and explanation

Correct answer: Oxidation

The addition of oxygen to a substance is called oxidation. For instance, magnesium combines with oxygen according to 2Mg + O₂ → 2MgO, so magnesium is oxidised. Reduction is generally associated with removal of oxygen or addition of hydrogen. Neutralisation involves acid and base, while displacement involves replacement of one element by another.
