Which material will rust the fastest

Postby Heather » Sat Feb 21, 2004 1:43 pm

We're working on our science project. I have three screws. Stainless, Zinc, and Brass. They are soaking in water right now, should I leave them in water or should I remove them so they can rust. I have never done this before. I feel stupid. Help.

First, don't feel stupid. This board is designed to help people with questions, no matter what the author thinks of his/her project.

Second, in order for something to rust, it needs air. Oxidation (the technical tern fro rust) is the same chemical process as burning something. Fire needs oxygen. It may begin rusting underwater because water naturally has oxygen in it (that's how fish survive), but it will rust water in air. The water provides the other element necessary for rust, surplus protons.
