Definitions of oxidation and reduction. Oxidation numbers. Redox equations. Oxidation - reduction. Oxidation is loss of electrons; Reduction is gain of electrons. 25 Jan Oxidation and reduction (Redox reactions) By Azfar Ali Bajwa 1. Oxidation and Reduction Reactions. Oxidation (Read only). Original definition: When substances combined with oxygen. Ex: All combustion (burning) reactions.
Oxidation-Reduction Reactions. The term oxidation was originally used to describe reactions in which an element combines with oxygen. Example: The reaction. PowerPoint Presentation. Oxidation (electron loss) always accompanies reduction (electron gain). The number of electrons gained by the oxidizing agent always equals the number lost by the reducing agent. Oxidation – reduction reactions (REDOX) - The chemical changes that occur when electrons are transferred between reactants. Assigning Oxidation Numbers.
No Slide Title. Recognize an oxidation-reduction reaction, in which electrons are transferred from one material (the substance that is oxidized) to another material (the substance that is reduced). Learn the role of oxidation/reduction in metabolism. In this section: oxidation and reduction; oxidation numbers; recognizing redox reactions; predicting redox reactions. Not from this section: a.
