Which of the following electrodes will act as a cathode, when connected with standard electrode (a) Als+3e Al; E° = -1.665V (c) Zn2+2eZn: E° = -0.76 V (b) Fe +2e Fe: E = -0.40 V (d) Ag +e>Ag: E° =+0.80 V Consider tho aall CANio142/1 a1 ni
cathode is the site of reduction so its reduction potential will be positive (likely to spontaneously reduce), and that the anode is the site of oxidation so its REDUCTION potentia...
