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!

Vinegar, which is an acid, is not conductive because usually there is too much water in it. Try the salt and vinegar combo to see if that does it. Remember, you need the ions in order to get a current to flow through the liquid, and the salt will break down into Na+ and Cl- to give you the ions you need. Try a sports drink, perhaps?
Hi Aurora,
Another great experiment. This was really fun. We tried OJ, milk, dish soap, vinager. We were suprised the vinager was not conductive and wondered if it was because of the sugar content in apple cider vinager. Or is vinager in general a base.
Just curious.
