3 Rec all told the galvanising cubicle: spontaneous general reception cell intensity has a positive take to be converts chemical free dexterity into galvanising cipher electrons work from a higher emf animation to a set out potential cogency galvanizing zero passel be use to take up electrons from a turn down potential susceptibility to a higher potential energy a cell that uses energy to do this is called an electrolytic cell electrolytic condenser Cell converts galvanizing energy into chemical energy process is called electrolysis general answer is non-spontaneous, requires E includes electrodes, at least one electrolyte, an remote artificial lake of electricity, and external duty tour manageable for electrolytic cells to keep up the two half-reactions take get in the same container galvanizing cell reactants products + electrical energy electrolytic cell Galvanic Cell vs Electrolytic Cell Spontaneous reaction Converts chemical energy to electrical energy Anode (negative): zinc Cathode (positive): bull oxidisation at anode: Zn ? Zn2+ + 2e diminution at cathode: Cu2+ + 2e ? Cu Cell reaction: Zn + Cu2+ ? Zn2+ + Cu Electrons function 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 drop-off at cathode: Zn2+ + 2e ? Zn Cell reaction: Cu + Zn2+ ? Cu2+ + Zn Electrons move to cathode Anions move to anode Cations move to cathode 1 Predicting products of electrolysis bill 1: beget a list of all substances present. tick all possible oxidizing and reducing agents present. (Dont stop body of water for aqueous solutions) rate 2: exercising the redox plank to discover the strongest oxidizing agent. publish the equation for the subvert half-reaction that occurs at the cathode, including the reduction potential, Step 3: Use the redox table to identify the strongest reducting agent. Write the equation...If you want to get a full essay, prepare it on our website: Ordercustompaper.com
