complete the following equation iron + oxygen water
Answers
Answer:
This results in oxidation of iron. Falls under metallic corrosion.
In simple terms addition of oxygen is called oxidation
We are adding oxygen to Fe in the presence of moisture
In this process the resulting product is iron oxide (Fe2O3) which is nothing but rust -a brownish red colour dust on surface of iron article.
It deteriorates the iron , reduces the quality and damages the important constructions like bridges, buildings and other monument in which iron is used as a strengthening material.
It is an electrolytic process Which involves a Redox reaction.
Any weaker site of the metal surface acts as anode (where oxidation takes place)
And the other side acts as Cathode (where reduction takes place).
We can prevent the rust formation by adding a coating of inert material such as paints on the surface. Which acts as a Barrier between the metal surface and atmosphere which ultimately prevents rust formation.
This is the reason Why you can find a paint coating on most of the iron articles.
