What is Difference Between Rusting And Corrosion- Best Answers

Hope you are also here to find what is the difference between rusting and corrosion? Or what is rusting? Or what is corrosion? Most of the times, the students appear to be confused when it comes to the difference between rusting and corrosion which results in their negative marking.

What is Rusting?

difference between rusting and corrosion

The difference between rusting and corrosion does not contain rocket science but it must be started from the basic concepts like what is rusting? I will not make this concept more complicated by using the complicated equations. In short, the uppermost layer of the iron, let’s say of a spoon made up of iron interacts with the oxygen (O2) present in the air in the form of the moisture, it results in the rusting of the iron spoon and eventually it’s colour may change to any of the following colours:-

  • Red
  • Orange
  • Brown
  • Or it may also be the combination of the all above colours.

This fluctuation in colours can be because of the amount of the oxygen or produces oxides.

How oxygen results in rusting?

I have already explained, what is rusting? and now it’s time to discuss the reason along with the logical equations. When the uppermost layer of the iron (Fe) reacts with the oxygen present in the air it results in the formation of iron oxide i.e. rust and I hope now you know what is rusting?

Chemical Equation:

2Fe + O2 → Fe2O3

What is Corrosion?

And here is now exact answer of what is corrosion? In short, corrosion can occur when a metal is exposed to the open atmosphere and unlike rusting, the corrosion can even occur ni the plastics but in a case of the plastic corrosion, it will be called as the degradation of the plastic.

Corrosion can damage the metal even more than that of the rusting. In the case of the corrosion, the metal starts getting damaged from the uppermost layer after reacting with the atmospheric gases (chemical gases) or water and slowly it results in the complete corrosion (complete breakdown of the metal into the small pieces and these pieces can even be on the atomic or sub-atomic level) and I hope now you know what is corrosion?

And if I summarise the all above explanations that you will come to know that the rusting is a sub-category of the corrosion.

Main Difference Between Iron And Corrosion

difference between rusting and corrosion

  • Corrosion of the things that contain iron in them is known as the rusting and it can also be called as the corrosion.
  • The corrosion of the things that are made up of the plastic is also a form of corrosion but in this case, it will be called as the degradation of the plastic.
  • Only iron oxide (or series of irons oxides is produced) in the case of the rusting whereas on the other hand corrosion can result in the formation of the oxides or even salts.
