Oksidantene
Oksidantene, or oxidizing agents, are chemical species that tend to cause oxidation in another compound during a redox reaction. This process involves the oxidizing agent accepting electrons from the other substance. As a result, the oxidizing agent itself is reduced. Common oxidizing agents include oxygen, halogens, peroxides, and nitric acid. Their ability to accept electrons is often quantified by their standard electrode potential. In organic chemistry, oxidizing agents are frequently used to convert alcohols to aldehydes, ketones, or carboxylic acids, and to introduce oxygen atoms into molecules. In biological systems, oxygen is the primary oxidizing agent, essential for cellular respiration, where it accepts electrons and protons to form water. The strength of an oxidizing agent varies considerably, with some being very powerful and capable of reacting with a wide range of substances, while others are milder. Understanding the properties and reactivity of oxidizing agents is fundamental in various fields, including chemistry, biology, and environmental science.
