Electrolysis Compounds are broken down into simpler substances using electricity. In order to work, ions must be free to move so need to be dissolved in water or melted Electrolyte The liquid that conducts electricity How does electrolysis work There is a flow of electrons that are taken away from the positive electrode and given to other ions at the negative electrode. As ions gain or lose electrons they become atoms/molecules and are then released. Positively charged ions move to negativ...
