Corrosion: The Chemical Process of Oxidation-Reduction

Each element of the periodic table belongs to the class of metal, nonmetal, or semimetal. Metals are the most common type and are defined by specific chemical and physical properties. The range of metals can be reduced by examining their chemical properties. They have a positive valence, which means that they provide electrons to the atoms to which they bind. Administration of negative electrons causes cations to form in the metal. (BrainPop) Since metals form cations, they can be oxidized and become susceptible to corrosion when exposed to moisture.

Redox (reduction-oxidation) reactions include all chemical reactions that change their oxidation state by atoms getting electrons (reduction) or losing electrons (oxidation). Substances capable of oxidizing other substances are said to be oxidizing and are called oxidizing agents, oxidizing agents or oxidizing agents. The oxidizing agent removes electrons from other substances. Similarly, substances capable of reducing other substances are said to be reducible and are called reducing, reducing or reducing agents.

Chemical reactions that transfer electrons between reactants are called redox reactions, redox reactions. During the oxidation process, the material loses electrons, making the material more active. In reduction, the material is reduced to acquire electrons or to make the material more negative. An electron donor is called a reducing agent because it reduces certain substances. Electron acceptors oxidize specific substances and are therefore called oxidants. Some redox reactions do not transfer electrons, but they change the electron sharing in the covalent bond.

In one definition, oxidation is explained as a process in which a species loses electrons, and reduction is a process by which a substance acquires electrons. In this way you can see how this pair must occur together. If a chemical loses its electron (and hence oxidized) it must have another interdependent chemical that can give these electrons to them. In this process, it is said that the second substance (substances that acquire electrons) is reduced. Without such an electron acceptor, the original species will not lose electrons and will not oxidize. When an electron acceptor is present, it is reduced to complete the redox binding process. This type of redox reaction can be summarized by a pair of equations. One is for electron loss (oxidation) and the other for electron gain (reduction). Using the above Daniell unit example,
