Designation for a system or a chemical reaction (artificial word from reduction and oxidation) in which a reaction partner is reductive (eg. oxygen
) and the second oxidative (eg, hydrogen). This means that the reducing agent (hydrogen) gives off electrons to the oxidant (oxygen). In the concrete example, water is created. With the reduction
So basically it's always one too oxidation
connected. Both processes together are partial reactions of a so-called redox reaction. These include many combustion and metabolic processes, such as fermentation
and the photosynthesis
The electrons released upon oxidation are taken up by the compound in reduction until equilibrium has occurred. The occurring voltage is called the redox potential. The wine contains both oxidative and reductive components. The redox potential expresses the sum of all possible reactions. However, the time period can not be determined until this equilibrium is reached. In the modern cellar technology can be derived from the redox potential partially required wine treatment measures.
