✴WHAT IS RUST?
✔You must have observed that when articles of iron are kept out in the open for some time, they get covered by a brownish substance. This brownish substance is called rust.
✴WHAT IS THE CAUSE OF RUSTING?
✔The two main factors that cause rusting are oxygen and water. As soon as the article comes in contact with air (oxygen) and moisture (water), it starts rusting.
✔ The chemical process that occurs during rusting can be represented as follows:
Iron (Fe) + Oxygen (O2) + Water (H2O) → Rust (Fe2O3)
✴WHAT ARE THE WAYS BY WHICH WE CAN PREVENT AN OBJECT TO BE RUSTED?
Four ways to prevent rusting are:-
✔By painting, oiling , gresing the metallic suface.
✔By galvanising the metal
✔By apply chromium over the metal.
✔By electroplating
