Electricity. Chemistry. Nothing in common, have nothing to do with each other. Wrong! Electrochemistry has been a fact since 1774. Once electricity was applied to particular solutions, changes occurred that scientists of the time did not expect.
In this lab, we will discover some of the same things that Farraday found over 300 years ago. We will be there as things tear apart, particles rush about, and the power of attraction is very strong. We’re not talking about dancing, we’re talking about something much more important and interesting….we’re talking about ELECTROCHEMISTRY!

Electricity travels when the atoms in a substance have extra electrons to carry that energy.
When something carries electricity, it is an electrical conductor. If an atom’s electrons are busy holding molecules together, then that substance can’t carry electricity, thus it is an electrical insulator. For instance, each atom in a copper wire has extra electrons, so copper is a good electrical conductor.
Pure, distilled water is an insulator. But water we encounter in day to day life contains other substances that make water electrically conductive.
The water in swimming pools contains many other substances that make it electrically conductive. Ocean water is conductive as well.
So, you said that water doesn’t conduct electricity. But what happens if lightning manages to zap a regular puddle of water? What about a public swimming pool? Would the chlorine effect the zap to become something more deadly? And what about the ocean water? Seeing it’s salty, would a lightning zap be fatal?
This rack came in the kit that used to be made by Home Training Tools. Any rack will work, I would recommend a regular test tube rack for these and future experiments!
Hi for this project, where can we find a rack like this one? Seeing many different racks other than this one. Thank you.
