Question

What are the essential conditions for rusting to take place?

Answer 1

Essential conditions for rusting:

• Rusting is the process of iron corrosion. The presence of air (oxygen) and moisture (Water) are the essential conditions for rusting to occur.
• When an object made of iron is exposed to moist air and water for a long time, it gets corroded and leads to the formation of a compound called ferric oxide or iron oxide $F{e}_2{O}_3$ also called rust.
• Oxidation of iron increases in the rusting process along with electron loss.
• The rusting process is accelerated by less active metals, acids, and the presence of the rust itself.
