What is a substance called when oxygen is added to it?
Answer and explanation
Correct answer: Oxidised
In the classical oxygen-transfer definition, addition of oxygen to a substance is oxidation. Therefore, the substance receiving oxygen is said to be oxidised. For example, magnesium gains oxygen to form magnesium oxide and is consequently oxidised. Reduction means removal of oxygen, neutralisation is an acid-base process, and precipitation is formation of an insoluble solid. Thus option A is correct.
