Introduction
You might have noticed how the iron railings in your balcony or terrace are shiny and bright when these are new but after a few weeks, the appearance of a reddish-brown layer on them? This is true for grills, nails, decor items made of copper, or even silver accessories. While copper starts to turn greenish over a period; silver starts to blacken. The reddish-brown layer on iron, the black layer on silver, and the green layer on the copper are all examples of corrosion.
Corrosion is a problem that causes extensive damages to things made out of metal. It includes bridges, railings, window grills, bodies of ships, locomotives, car bodies, and all other metallic objects. It is an irreversible reaction; which is why it is so very important to understand the basics of corrosion and its prevention properly. Use an advanced learning app like MSVgo that helps you understand the fundamentals of corrosion (and preventing it) in an engaging and immersive manner with the help of animations and visualizations.
Let us now understand corrosion and its prevention in detail.
Corrosion is a natural irreversible chemical reaction in which chemically-active metals convert from their pure state to corroded substances, in the presence of moisture or air.
Corrosion Examples And Reactions
These are the factors that cause corrosion:
Corrosion is one of the most common chemical reactions that happen in our everyday life. It happens when metals react or are acted upon by other substances like oxygen, acids, moisture, etc.
Corrosion can be prevented by methods like painting, galvanizing, anodizing, alloying, and chrome-plating.
Corrosion is the degradation of reactive metals, and you need to study it in class 10 in Chemistry as this is a natural process and needs to be prevented.
The best three ways to prevent corrosion are painting, alloying and chrome-plating.
Rust is a common example of corrosion. Silver turning black and copper turning green are other two common examples.
Aluminum is the only reactive metal that does not corrode. A protective layer on the surface prevents it from corrosion.
For a better understanding of corrosion and its prevention, use a powerful app like MSVgo that will act as a catalyst in your learning experience. This is because it enables clear understanding in an animated setup with visualization aids and techniques.
