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. Caffeine is composed of atoms
