I put a penny in vinegar. I came clean. I added a nickle and a dime along with the penny. The nickle and dime are now turning copper. Why does this happen? I am a 8th grade teacher,and all the kids are asking me. I also have a penny in bleach. It did not do anything for a week. Now the bleach is all black and the penny is collecting a greenish-white substance. What is happining chemically in both these cases?
