Chapter 17, Problem 39P

1) The first part was testing the observed vs theoretical cell potentials for the following voltaic cells: Zn/Cu reading was 0.914  Zn/Al reading was 0.210 Zn/Ag reading was 1.330 Al/Cu reading was 0.672 Ag/Cu reading was 0.413 Ag/Al reading was 1.000 Now using the information above calculate the Percent error of measured voltages to calculated predicted voltages for each combo 2) For the second part of the experiment, I constructed an electrolytic cell using 2.008 grams of KI in about 100mL of DI water. I measured the pH of the reaction mixture which was 5.22 with soultion in plain water and 10.74 with soultion added.  Calculate using your measured pH values at the beginning and end of the reaction, determine the mass of I2 produced

Write out what data and information you plan to collect during the experiment of electrochemistry redox reaction (Oxidation Reduction) to answer how will a species be reduced or gain electrons when a species is oxidized??Then list the equations and formulas you plan to use to manipulate that data.Also list how many trials you plan to do?
