effect of pH on Copper Corrosion

Postby marinablue » Thu Feb 17, 2011 8:08 am

I am doing my science fair project on the above subject that I got from your website. I did the experiment using pennies in both the water and vinegar solutions, and then tested the solutions for the presence of copper. How do I clearly state this in a hypothesis, and how should I chart my results? The graphs are due tomorrow and I need help.
