Question

What is the best way to prevent a screwdriver from rusting when not in use.

Answer 1

1. When metals come in contact with air and moisture, they undergo oxidation which is called corrosion.
2. Rusting is one of the most eminent problems that all the workers working with tools and machines face.
3. The reaction of the formation of rust would be: $\underset{\left(Iron\right)}{\underbrace{4Fe\left(s\right)}}+\underset{\left(Oxygen\right)}{\underbrace{3O_2\left(g\right)}}+x.H_{2}O\left(l\right)\to \underset{\underset{(Reddish-brown)}{\underbrace{\left(Rust\right)}}}{\underbrace{2F{e}_2{O}_3.x.H_{2}O}}$
4. The best ways to prevent a screwdriver from rusting when not in use are:
5. Very first we have to place it in a clean and dry place and we should avoid getting tools wet.
6. By applying oil, grease, or paint, the surface becomes waterproof and the moisture and oxygen present in the air cannot come into direct contact with iron. Hence, rusting can be prevented.
7. Galvanization: It is the process of applying a protective layer of zinc on a metal which is a very common method of preventing the rusting of iron.
