How Corrosion of iron in presence of moist air?

When iron is exposed to moist air, it can undergo a chemical reaction known as corrosion. The moisture in the air reacts with iron to form iron oxide, also known as rust. This process is accelerated in the presence of salt or pollutants in the air, which act as catalysts for the corrosion of iron. Regular maintenance and protective coatings can help prevent corrosion of iron in moist air environments.
