Electrolysis Process by which an electric current is passed through a substance to cause a chemical change The chemical change is one in which the substance loses or gains an electron Electrolysis. Pg. 658 - 660. Let’s talk about the lab…. In lab the reactions were spontaneous!. The solutions were arranged so that the electrons would move through the wires. Voltaic cells involving spontaneous reactions are typically used to run motors and perform other useful work. LQ: What happens at the electrodes?. Learning outcomes. I can describe electrolysis as the decomposition of an electrolyte with an electric current – Grade B. I can describe the changes at the electrodes during electrolysis – Grade A. Electrolysis .
