Oxidation facts for kids
Oxidation is the opposite of reduction. A reduction-reaction always comes together with an oxidation-reaction. Oxidation and reduction together are called redox (reduction and oxidation). Oxygen does not have to be present in a reaction, for it to be a redox-reaction.
In terms of oxygen transfer
Oxidation is a gain of oxygen. Reduction is a loss of oxygen. For example:
- Fe2O3 + 3CO → 2Fe + 3CO2
Both reduction and oxidation go on at the same time which is a redox-reaction. The loss of Hydrogen-atoms; and, the simultaneously gaining of oxygen-atoms, is known as oxidation.
Images for kids
Sodium and fluorine bonding ionically to form sodium fluoride. Sodium loses its outer electron to give it a stable electron configuration, and this electron enters the fluorine atom exothermically. The oppositely charged ions are then attracted to each other. The sodium is oxidized, and the fluorine is reduced.
