How and Why does Copper Oxidize
I am working on my science project for school. I want to show how and why copper oxidizes, and what happens to copper when exposed to different solutions. For my experiment, I have chosen to work with vinegar [in bulk on eBay or Amazon], vegetable oil, and Del Taco hot sauce (at the request of my teacher.)
Can you help with this as I cannot seem to find any good references on the web?

DEAR ASHLEY,
I AM ALSO DOING A SCIENCE PROJECT ABOUT THE SAME TOPIC. I DON'T KNOW ANY GOOD WEB SITES BUT THERE IS ONE THING THAT IS SURE TO TURN YOUR COPPER GREEN . . . . . BLEACH REGULAR LIQUID LAUNDRY BLEACH [adv: bleach/sodium hypochlorite in bulk on eBay or Amazon] . I HOPE THIS CAN HELP AND GOOD LUCK!
SINCERELY,

A good website is www.newton.dep.anl.gov/askasci. You have to search but it has good information.

When copper turns green it is because it is exposed to oxygen and possibly water.

I'm doing a experiment like that too I'll try bleach. So thanks.
