About how long does it take for nails to rust?

i want to do a science project with rusting nails. Which nails rust the fastest? how fast do they rust? Is there something else like coins that rusts faster? thx!About how long does it take for nails to rust?
Nails (or any other steel or iron without any plating, paint or other protective coating) will start to get rusty withing a few days if kept in a wet environment. Of course, this will be just a light coating, if you need heavy, scaling rust, it might take quite a while even with salt water.About how long does it take for nails to rust?
It would depend on what the nail was made out of and what it was exposed to. A nail will rust faster if it is used in a saltwater enviroment like a coastal area, than the same nail used in a dessert with little moisture. Maybe you could take a box of the same nails and put one in different solutions and see how they react. Put one in salt water, one in tap water, one in acid, also use one as a positive anode in electrolisis. Monitor the time and rates of rusting and deterioration. Or place different nails in the same solution and see which rusts first and how badly.
Not sure how long it takes. But I guess you can find out!





Do not use coins, they contain copper and are not going to rust.





Do not use galvanized nails as they are coated to prevent rusting.





Do not use dipped nails, as they are coated to prevent rusting.





Get a ';standard'; nail (indoor use, not outdoor use) for your experiment.





Compare speed to rust with plain water and salt water to see if one rusts faster. (one will rust faster).
