POST LABORATORY QUESTIONS After Laboratory Homework Part 1 You have assumed your reference metal had a zero voltage contribution for your cell; have the relative voltage of each of the other four metals. You are to calculate the voltage of the oxidation of your reference metal by adjusting each metal to the DEFINED scale relative to SHE. Anode + Cathode = Voltage Reading so, Anode = Voltage Reading - Cathode 1.(a) Find the Reduction Potentials for your metal ions to the metal: Fe3+ to Zn2+ = 0.352 V, Cu2+ to Zn2+ = 0.270 V, Co2+ to Zn2+ = 0.254 V, Al3+ to Zn2+ = 0.479 V. 1.(b) Calculate your Anode from your Measured Voltage Reading and the Reduction Potential, voltage, of each metal. 1.(c) Calculate the average value of your Anode. 1.(d) Convert your voltage of the oxidation of the Anode to the reduction potential of your reference metal ion. 1.(e) Calculate the percent difference of your reference metal ion reduction potential to the reduction…
