Question

What would hapoen to the iron railings on the road side if they are not painted ? Why does it happen so ?

Answer 1

If the iron railing on the road side is not painted, a brown rust would form on its surface because the moist air of the atmosphere reacts with iron to form brown flaky substance on its surface. The rust is hydrated iron (III) oxide, Fe203.xH20.

Answer 2

Hii There!!!


When iron railings on the road side are not painted, they gets corroded due to the moisture and air present in the atmosphere.
Since, corrosion is a wasteful process tonnes of iron gets wasted in a country.


This process happens when surface of metal are attracted by moisture and air.
This process is commonly known as "Rusting of Iron".
