Mnemonic Device: OIL RIG; Explanation: to remember that Oxidation Is Loss, Reduction Is Gain. An OIL RIG Cat At the Anode, Oxidation Is Loss and Reduction Is Gain at the Cathode
Oxidation is loss of electrons (OIL RIG). That means that an oxidising agent takes electrons from that other substance. So an oxidising agent must gain electrons. Or you could think it out like this: An oxidising agent oxidises something else. That means that the oxidising agent must be being reduced. Reduction is gain of electrons (OIL RIG).
In chemistry, OIL RIG is a mnemonic device to help students remember the difference between oxidation and reduction. It stands for "Oxidation is loss, reduction is gain." It refers to the transfer of oxygen, hydrogen and electrons during a reduction-oxidation reaction between two molecules.
Oxidation describes the loss of electrons by a molecule, atom or ion Reduction describes the gain of electrons by a molecule, atom or ion Which gains and loses electrons can be easily memorised by the abbreviation OIL RIG, which stands for, "Oxidation Is Loss," or losing electrons, and "Reduction Is Gain," or gaining electrons.
So, remember the modern definition of oxidation and reduction concern electrons (not oxygen or hydrogen). One way to remember which species is oxidized and which is reduced is to use OIL RIG. OIL RIG stands for Oxidation Is Loss, Reduction Is Gain.

OIL RIG is - Oxidation Is Lose, Reduction Is Gain. Gaining/losing ions during electrolysis. At positive and negative electrodes. Don't know the others sorry xx
OIL RIG. Oxidation Is Loss, Reduction Is Gain. In other words, when a material or molecule is oxidized, it simply means it has lost electrons. It has nothing to do with just sticking oxygen into the mix, and is a very broad way to describe a particular chemical change where electrons are either bound tightly or shared. Oxygen in the air is ...

Oxidation and reduction are two types of chemical reactions that often work together.Oxidation and reduction reactions involve an exchange of electrons between reactants. For many students, the confusion occurs when attempting to identify which reactant was oxidized and which reactant was reduced.
