Oksüüduse

Oksüüduse refers to the process of oxidation, a fundamental chemical reaction. In this process, a substance loses electrons, leading to an increase in its oxidation state. Oxidation is often accompanied by a simultaneous reduction, where another substance gains electrons and experiences a decrease in its oxidation state. These two processes, oxidation and reduction, always occur together and are collectively known as redox reactions.

A common example of oxidation is the rusting of iron. When iron comes into contact with oxygen and water, it undergoes oxidation, forming iron oxides. Another familiar example is the burning of fuel, such as wood or natural gas. In combustion, the fuel is oxidized by oxygen, releasing energy in the form of heat and light. Our bodies also rely on oxidation for energy production through cellular respiration, where glucose is oxidized.

The term "oxidation" was originally coined because oxygen was frequently involved in these reactions. However, it has since been broadened to include any process where electrons are lost, regardless of whether oxygen is present. Reversing an oxidation process typically involves reduction. Understanding oxidation is crucial in many scientific fields, including chemistry, biology, and environmental science, as it plays a role in everything from industrial processes to biological functions.
