oksidasjonsagent
An oksidasjonsagent, also known as an oxidizing agent or oxidant, is a substance that causes oxidation in another substance. In a chemical reaction, the oksidasjonsagent itself is reduced, meaning it gains electrons. Oxidation, in turn, is the process where a substance loses electrons. Therefore, an oksidasjonsagent is a species that accepts electrons from another species. Common examples of oksidasjonsagenter include oxygen (O2), halogens (like Cl2 and Br2), and permanganate ions (MnO4-). The strength of an oksidasjonsagent is measured by its standard electrode potential. A stronger oksidasjonsagent has a higher standard electrode potential. The process of oxidation and reduction, often referred to as redox, always occurs simultaneously. When one substance is oxidized, another must be reduced, and the substance that causes the oxidation is the oksidasjonsagent. Understanding the role of oksidasjonsagenter is fundamental in many chemical processes, including combustion, corrosion, and electrochemistry.
