Question

What is corrosion of iron called?

Answer 1

1. Many materials go through chemical changes over time when exposed to the atmosphere.
2. The process of degradation of any metals is called corrosion.
3. Corrosion generally happens to iron and alloys of steel.
4. When iron comes in contact with air containing Oxygen and water then it corrodes the upper layer of Iron.
5. This forms a reddish-brown color flaky substance called rust and the phenomenon is called rusting of Iron.
6. The chemical reaction related to rusting of Iron is represented as follows:
   $4\mathrm{Fe}\left(\mathrm{s}\right)+3{\mathrm{O}}_2\left(\mathrm{g}\right)+2{\mathrm{xH}}_2\mathrm{O}\left(\mathrm{l}\right)\to 2{\mathrm{Fe}}_2{\mathrm{O}}_3.{\mathrm{xH}}_2\mathrm{O}\left(\mathrm{s}\right)$
7. The term “rusting” generally refers to the corrosion of iron objects.
