Part 1: Percent Error Calculation for Voltaic Cells
To calculate the percent error, use the formula:
Percent Error=Theoretical Value∣Observed Value−Theoretical Value∣×100
Theoretical Voltages for Voltaic Cells
To calculate the percent error, we first need the theoretical standard electrode potentials for the voltaic cells:
Zn/Cu:
EZn2+/Zn = −0.76 V
ECu2+/Cu = +0.34 V
Theoretical: Ecell =0.34−(−0.76) = 1.10 V
Zn/Al:
EAl3+/Al = −1.66 V
Theoretical: Ecell = −1.66−(−0.76) = −0.90 V
Zn/Ag:
EAg+/Ag = +0.80 V
Theoretical: Ecell = 0.80−(−0.76) = 1.56 V
Al/Cu:
Theoretical: Ecell = 0.34−(−1.66) = 2.00 V
Ag/Cu:
Theoretical: Ecell = 0.34−0.80 =…
