If you want it to rust 100 %
The normal limit of iron in well water is typically around 0.3 milligrams per liter (mg/L). High levels of iron in well water can lead to staining of fixtures and laundry, as well as affect the taste and odor of the water.
In order for you to keep your iron pot from rusting, you will need to keep it away from any water or moisture. I have also found that coating the iron, such as a seal or paint will dramatically limit the amount of rusting.
Its the moisture which causes rusting of iron
Yes, iron rusts when exposed to moisture and oxygen. Rust is a chemical reaction that occurs on the surface of iron when it comes into contact with water and oxygen, forming iron oxide.
iron, moisture and air
Depends what you call "too much". The current acceptable limit is now 3ppm, but I have seen people drinking with over 8 ppm and not being bothered by it.
Ammonia solution is used in the iron limit test to precipitate iron as iron(III) hydroxide. This allows for easy separation and identification of iron in the solution. The formation of a yellow-orange precipitate indicates the presence of iron.
Rusting is caused due to exposture of iron to moisture. When iron articles are painted, it is not exposed to the atomospheric moisture. This is how paint stops rusting
Yes, every material has its limit in this respect.
iron, moisture and air
Coating prevent the iron from contacting air and moisture. So it prevents iron from rusting.
iron rusts faster in presence of moisture and air.
