👉 A process or action that involves converting a chemical compound into its oxidized form, often in the presence of oxygen. This is typically done to improve the stability and reactivity of the compound. The reaction can involve various steps such as reduction, oxidation, or addition. For example, when you add a certain amount of a strong acid (such as hydrochloric acid) to a substance that's already oxidized (like iron), you get a product called "protoxidized" iron
