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.

What you mean by oxidation?

Oxidation is defined as a process in which an electron is removed from a molecule during a chemical reaction. ... In other words, during oxidation, there is a loss of electrons. There is an opposite process of oxidation known as a reduction in which there is a gain of electrons.

Where does oxidation occur?

If a chemical species loses one or more electrons, this is called oxidation. The opposite process, the gain of electrons, is called reduction. Oxidation occurs at the Anode. Reduction occurs at the Cathode.
