Question

For prevention of rusting of iron, which paints are used?

Answer 1

to prevent corrosion we use
paints
galvanization
applying oil or grease
because these things prevent from getting oxidised in atmosphere

Answer 2

Explanation:

Rusting is defined as a process of corrosion of iron due to the deposition of an oxide layer on its surface.

Chemical formula of rust is $Fe_{2}O_{3}.xH_{2}O$.

Usually, oil, grease, paints etc are applied on the surface of iron to avoid rusting.

A paint containing red lead, that is, $Pb_{3}O_{4}$ helps in prevention of rusting of iron.

Therefore, we can conclude that paints with $Pb_{3}O_{4}$ are used for prevention of rusting of iron.
