Bitesize oxidation and reduction

WebOxidation and reduction take place together at the same time in the same reaction These are called redox reactions Oxidation is a reaction in which oxygen is added to an element or a compound Reduction is a reaction in which oxygen is removed from an element or compound Example: Identifying the loss and gain of oxygen in an equation

Oxidation and reduction - BBC Bitesize

WebAug 2, 2024 · Reduction involves a half-reaction in which a chemical species decreases its oxidation number, usually by gaining electrons. The other half of the reaction involves oxidation, in which electrons are lost. Together, reduction and oxidation form redox reactions (reduction-oxidation = redox). WebApr 8, 2024 · Oxidation is the gain of oxygen. Reduction is the loss of oxygen. For example, in the extraction of iron from its ore: Because both reduction and oxidation are occurring simultaneously, this is known as a redox reaction.
