Electrical conductivity One to five percent of the caffeine molecule dissociates in water‚ proving that the compound is a weak electrolyte. A substance that completely dissociates in a solution‚ such as water‚ is considered an electrolyte and can therefore conduct electricity. This dissociation is caused by the atoms’ minimal nuclear charge‚ allowing the substance to break apart entirely into its ions. Ions are mobile‚ which induces a current and contributes to the substance’s high electrical conductivity

If there are more coins in the pile‚ then the more electricity it can produce‚ because the more electrons you have‚ the more electricity you will get. Batteries are expensive‚ but you can make one for exactly 24 cents! In this experiment‚ you will make your own voltaic pile using
