The way to prevent oxidation, caused by oxygen, is to provide a layer of shielding between the material and the air.
They both offer and produce a polyurethane coating on the surface of metal objects or a quick spray of an anti-oxidant. Destructive oxidation cannot occur if the oxygen cannot penetrate a surface to reach the bare surface to corrode. Oxidation according to Dictionary. Oxidizing is: to convert an element into an oxide; combine with oxygen. What Causes Oxidation? How Do You Prevent Oxidation? Related Post.

The best…. In this reaction, hydrogen is being oxidized and fluorine is being reduced. The reaction may be better understood if it is written in terms of two half-reactions. Note there is no oxygen anywhere in this reaction!
An older meaning of oxidation was when oxygen was added to a compound. This was because oxygen gas O 2 was the first known oxidizing agent. While the addition of oxygen to a compound typically meets the criteria of electron loss and an increase in the oxidation state, the definition of oxidation was expanded to include other types of chemical reactions.
A classic example of the old definition of oxidation is when iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust. The chemical reaction is:. The iron metal is oxidized to form the iron oxide known as rust.
Electrochemical reactions are great examples of oxidation reactions. When a copper wire is placed into a solution that contains silver ions, electrons are transferred from the copper metal to the silver ions.
The copper metal is oxidized. Silver metal whiskers grow onto the copper wire, while copper ions are released into the solution. Another example of oxidation where an element combines with oxygen is the reaction between magnesium metal and oxygen to form magnesium oxide. Many metals oxidize, so it's useful to recognize the form of the equation:. Once the electron was discovered and chemical reactions could be explained, scientists realized oxidation and reduction occur together, with one species losing electrons oxidized and another gaining electrons reduced.
A type of chemical reaction in which oxidation and reduction occurs is called a redox reaction, which stands for reduction-oxidation.
The oxidation of a metal by oxygen gas could then be explained as the metal atom losing electrons to form the cation being oxidized with the oxygen molecule gaining electrons to form oxygen anions.
In the case of magnesium, for example, the reaction could be rewritten as:. Oxidation in which oxygen is involved is still oxidation according to the modern definition of the term. However, there is another old definition involving hydrogen which may be encountered in organic chemistry texts. This definition is the opposite of the oxygen definition, so it may cause confusion. Still, it's good to be aware.
According to this definition, oxidation is the loss of hydrogen, while reduction is the gain of hydrogen.
