A redox reaction involves the transfer of electrons.
Redox is the name given to a chemical reaction that involves the transfer of electrons between different reactants, which leads to a modification of the oxidation state. In these reactions, one element loses electrons and the other receives them.
The term redox refers to the REDuction-OXidation that occurs within the framework of the reaction. There is an element that accepts the electrons released by the other and is reduced when its oxidation state is minimized. The element that is responsible for the release of electrons, for its part, is oxidized. While the element that gains electrons is known as an oxidizing agent , the element that releases them is called a reducing agent .
A combination of processes
The redox reaction , in short, is a combination between a reduction process (an element captures electrons and reduces its oxidation state) and an oxidation process (an element releases electrons and increases its oxidation state).
These two processes are actually two simultaneous facets of reduction, which are always carried out together. Every time there is an element that is oxidized by releasing electrons, there is another that accepts them and is reduced.
Redox reaction in a swimming pool
Within the field of swimming pools, the concept of Redox that concerns us has acquired special value in recent years. And in them this becomes a fundamental part when it comes to ensuring that these facilities have the so-called salt chlorination. Specifically, it is used for those that have it, that is, salt water, and need to have an adequate state of the water so that bathers do not run any type of risk.
Thus, it is said that Redox values are used to keep the different chemical processes in the water under control as well as to measure them and verify that they adjust to the parameters that are necessary for the safety of those who use the pools.
With a redox reaction, a change in the oxidation state of the elements occurs.
Regarding this type of value, it is worth knowing the following data:
-Its electrode is similar to that of the PH with the exception that noble metals are used to measure it, because they do not interfere in any way with the chemical reaction that will be carried out in the pool.
-Indicates whether the water in said aquatic facility tends to accept or lose electrons.
-It is calculated that the aforementioned pool water in question is disinfected and is appropriate if its Redox potential ranges between 650 and 750 minivolts (mV). If it does not comply with this measure, it will be necessary to proceed to solve it through the corresponding use of products and chemical actions.
The concept in the industry
Knowledge of redox reactions is very useful in different sectors of industry. By encouraging or inhibiting these processes, according to the need, products can be generated that arise after the reduction of an element.
You can even act on the corrosion that certain materials experience when they rust. That is why the notion has great importance in the industrial field.
