Rust,corrosion experiment,please help?!?!?!?!?!?!?!?
I need help.im in 9th grade and i need to do a research project that has to be pretty advanced.right now im going to do an experiment where im take nails comparing them to see which one rust fast like,one will be a regualr steel one,one will be painted,one will be galvanized and there will two nails used together as cathode protection.how can i make it better?i need answeres asap,please!!!!!!!!!!!!!!!!!!!!!!!!
One suggestion I would make is to use several nails of each type. Carefully weigh them before and after the experiment, and accurately record your results. Unless you have a very long time in which to do your experiment, I would also suggest that you expedite the process by exposing the nails to a corrosive environment. This could be done by placing the nails in a big jar that has a small beaker of concentrated hydrochloric acid. Seal the jar and see what happens. It should take a lot less time that simply exposing them to air. Or you could possibly put the nails into a weak acid like a carbonated soft drink.
I think that I’d boil them in different solutions.
Try high-vinegar solution (Your family will love your experiment’s odor)
Try high-salt solution
Try the difference between very strong coffee and decafeinated coffee. (I heard that Sikorski’s in Conn. actually uses some kind of caffeine to clean engine parts–true or myth???
Boil all of them, it will hasten the effects, but make note in your project that heat was used as one factor.
Good luck…I miss those high school science projects!
