Redox reaction

Redox Reaction

A Redox Reaction (or 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'.

Overview

In a redox reaction, the oxidizing agent gets reduced due to the gain of electrons, while the reducing agent gets oxidized due to the loss of electrons. This simultaneous oxidation and reduction process is what characterizes redox reactions.

Oxidation and Reduction

Oxidation is the process of losing electrons, while Reduction is the process of gaining electrons. These two processes always occur together in a redox reaction. The substance that loses electrons is known as the reducing agent, while the substance that gains electrons is known as the oxidizing agent.

Examples of Redox Reactions

Redox reactions are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.

Redox Reactions in Biology

In biological systems, redox reactions occur during the process of cellular respiration. In this process, glucose and other organic molecules are broken down in cells to produce energy, releasing carbon dioxide and water as byproducts.

Redox Reactions in Chemistry

In chemistry, redox reactions are involved in many processes, including the extraction of metals from their ores, battery operations, and the process of electrolysis.
