Simple chemical tests are described that can indicate the presence of certain metals in coins. A wide variety of chemical concepts are involved. The experiments described are a natural fit for the 2019 National Chemistry Week theme of "Marvelous Metals!"
National Chemistry Week
This post describes some simple experiments using various coins and neodymium magnets that connect to the 2019 National Chemistry Week theme of Marvelous Metals!
I have been in the lab conducting tests on the chemical and physical properties of various geological samples. In my investigations I’ve found that hematite is a particular mineral that is easy to acquire and quite amenable to experimentation.
