Answer» Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases. An example of a reaction is that between hydrogen and fluorine gas to form hydrofluoric acid: H2 + F2 → 2 HF In this reaction, hydrogen is being oxidized and fluorine is being reduced. The reaction may be better understood if it is written in terms of two half-reactions. H2 → 2 H+ + 2 e- F2 + 2 e- → 2 F- Note there is no oxygen anywhere in this reaction! The process of oxidizing or any substance is oxidized is known as oxidation. |
