What is redox in chemistry

Reduction is the process of gaining electrons and resulting in a drop in the oxidation state of a reactant. Oxidising agents are electron-accepting species that experience a decrease in the oxidation state in a redox reaction. Reducing agents are electron-donating species that experience an increase in the oxidation state in a redox reaction.

Aug 29, 2023 · Redox reactions: these are or oxidation-reduction reactions that involve trans- fer of electrons. As the electron transfer occurs, substances undergo changes in oxidation number. Reduction: the process by which a compound gains or appears to gain electrons. It corresponds to a decrease in oxidation number. By assigning oxidation numbers to the atoms of each element in a redox equation, we can determine which element is oxidized and which element is reduced during the reaction. In this video, we'll use this method to identify the oxidized and reduced elements in the reaction that occurs between I⁻ and MnO₄⁻ in basic solution. Created by Sal ...By looking at each element's oxidation state on the reactant side of a chemical equation compared with the same element's oxidation state on the product side, one can determine if the element is reduced or oxidized, and can therefore identify the oxidizing and reducing agents of a chemical reaction.Reduction involves gain of electrons, so the tendency of an electrode to gain electrons is called its reduction potential. The equilibrium potential difference between the metal electrode and the solution surrounding it is called the electrode potential. It is also defined as the tendency of an electrode to lose or gain electrons.Tell-Tale Signs of a Redox Reaction.
