Redox reaction
Redox Reaction
A Redox Reaction (pronounced: /ˈriːdɒks/), also known as oxidation-reduction reaction, is a type of chemical reaction that involves a transfer of electrons between two species. The term "redox" comes from two concepts involved with electron transfer: Reduction and Oxidation.
Etymology
The term "redox" is a portmanteau of the words "reduction" and "oxidation". The concept is often attributed to French chemist Antoine Lavoisier, who introduced the idea in the 18th century.
Definition
In a redox reaction, the oxidizing agent gets reduced due to the gain of electrons, and the reducing agent gets oxidized due to the loss of electrons. This simultaneous oxidation and reduction process is what characterizes redox reactions.
Related Terms
- Oxidizing Agent: A substance that has the ability to oxidize other substances, meaning it causes them to lose electrons.
- Reducing Agent: A substance that has the ability to reduce other substances, meaning it causes them to gain electrons.
- Half-Reaction: Either the oxidation or reduction reaction component of a redox reaction.
- Electrochemistry: The study of chemical reactions that cause electrons to move about. This movement of electrons is called electricity, which can be generated by movements of electrons from one element to another in a reaction known as an electrochemical reaction.
