chemical tests on coins
// Monday, September 16, 2019 Tom Kuntzleman
I recently shared some simple experiments using magnets and coins that connect to the 2019 National Chemistry Week (NCW) theme, “Marvelous Metals!”1 Because coins are familiar items, made of metal, and so very easy to obtain, I think doing experiments with coins is a great idea for NCW 2019!
Bouncing batteries

Did you know there is a simple test you can do to see if an alkaline battery is fresh or dead?1,2 All you need to do is bounce the bottom of a battery onto a hard, flat surface. If the battery is fresh it won’t bounce very well. If the battery is dead, it will bounce very high. Check it out in the video.3
aluminum reacts with copper solution

Displacement reactions are an essential way to demonstrate the reactivity series of metals. I have tried many different methods to demonstrate or perform displacement reactions over the years with mixed results regarding one particular metal, aluminium.
Starting materials for demonstration

I found a version of this demonstration online a couple of years ago. I admit, when I first tried it with my class it was mostly for a crowd pleaser to demonstrate the activity series of metals, but I then became very intrigued by the processes occurring.
Silver plate: before and after

I recently gave a public lecture on my campus in which (among other things) I discussed the chemistry of metallic copper, silver, and gold.
