3 Recall the galvanic cubicle: spontaneous overall reception cellphone effectiveness has a positive regard as converts chemical free efficacy into galvanising cipher electrons liquefy from a higher potential vital force to a level potential efficiency galvanic energy passel be employ to range electrons from a lower potential energy to a higher potential energy a cell that uses energy to do this is called an electrolytic cell Electrolytic Cell converts electrical energy into chemical energy process is cal led electrolysis overall answer is non-spontaneous, requires E includes electrodes, at least one electrolyte, an external faux lake of electricity, and external circuit possible for electrolytic cells to have the ii half- receptions take place in the same container galvanic cell reactants products + electrical energy electrolytic cell Galvanic Cell vs Electrolytic Cell Spontaneous answer Converts chemical energy to electrical energy Anode (negative): zinc Cathode (positive): copper Oxidation at anode: Zn ? Zn2+ + 2e diminution at cathode: Cu2+ + 2e ? Cu Cell reaction: Zn + Cu2+ ? Zn2+ + Cu Electrons move to cathode Anions move to anode Cations move to cathode Non-spontaneous reaction Converts electrical energy to chemical energy Anode (positive): copper Cathode (negative): zinc Oxidation at anode: Cu ? Cu2+ + 2e Reduction at cathode: Zn2+ + 2e ? Zn Cell reaction: Cu + Zn2+ ? Cu2+ + Zn Electrons move to cathode Anions move to anode Cations move to cathode 1 Predict ing products of electrolysis bill 1: Make ! a list of all substances present. tick all possible oxidizing and trim back agents present. (Dont forget body of water for aqueous solutions) blackguard 2: Use the redox plank to diagnose the strongest oxidizing agent. issue the equation for the step-down half-reaction that occurs at the cathode, including the reduction potential, Step 3: Use the redox table to identify the strongest reducting agent.
