Question
Can someone please help me with filling in Table 1 and Table 2? The second picture is the experimental data.
In case you can't read them, the E(V)(Lit) Values are:
1) .463
2) .463
3) 1.100
4) .926
5) .637
6) 1.562

Standard Reduction Potentials From the experimental results in Table 1, deduce the standard half-cell reduction potentials relative to the copper ion-copper metal pair as Eo 0.Explanation / Answer
Solution:
The computation are expressed below,
1) Ag+ + e- = Ag +0.80 V
Cu2+ +2e- = Cu +034 V
E = 0.8-0.34 = 0.46V
2) Pb2+ + e- = Pb -0.13 V
Cu2+ +2e- = Cu +0.34 V
E = 0.34 - (-0.13) = 0.47 V
3) Zn2+ + 2e- = Zn -0.76 V
Cu2+ +2e- = Cu +0.34 V
E = 0.34 - (-0.76) = 1.10 V
4) Pb2+ + e- = Pb -0.13 V
Ag+ + e- = Ag +0.80 V
E = 0.80- (-0.13) = 0.93 V
5) Zn2+ + 2e- = Zn -0.76 V
Pb2+ + e- = Pb -0.13 V
E = -0.13 - (-0.76) = 0.67 V
6) Zn2+ + 2e- = Zn -0.76 V
Ag+ + e- = Ag +0.80 V
E = 0.86 - (-0.76) = 1.56 V
