Oksüütsiooni

Oksüütsiooni is a chemical process involving the loss of electrons by a molecule, atom, or ion. This loss of electrons results in an increase in its oxidation state. In simpler terms, it is often associated with the addition of oxygen or the removal of hydrogen. However, the fundamental definition revolves around the transfer of electrons. A common example of oxidation is the rusting of iron, where iron atoms lose electrons to oxygen. Another everyday example is the browning of a cut apple, which is a result of enzymatic oxidation.

Oxidation is always accompanied by a reduction, which is the gain of electrons. These two processes together form a redox reaction. The substance that loses electrons (is oxidized) is called the reducing agent, and the substance that gains electrons (is reduced) is called the oxidizing agent. In biological systems, oxidation plays a crucial role in metabolism. For instance, cellular respiration involves the oxidation of glucose to produce energy.

In organic chemistry, oxidation can lead to various functional group transformations. For example, primary alcohols can be oxidized to aldehydes, and further oxidation can yield carboxylic acids. The degree of oxidation can be determined by assigning oxidation states to individual atoms within a molecule. Understanding oxidation is fundamental to many fields, including chemistry, biology, and environmental science.
