1. The problem statement, all variables and given/known data I have been given the task to corrode brass with common base, acid and salt. I understand that it is an alloy of copper and zinc and is actually designed not to rust. Before I begin the experiment, I am looking for the best TYPE of brass to use in this experiment. Given that there appears to be hundreds of different types of brass with different properties, which type will give me the best chance for visible results? 2. Relevant equations Brass is an alloy of copper and zinc 3. The attempt at a solution I have looked all over the internet... and have contacted several "brass wholesale suppliers" who have simply stated that they are not "scientists."
