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

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
