Build the followingelectrochemical cells as shown in Figure 1, andcomplete Table 2 in the Data andCalculations section. To build a galvanic cell, you onlyneed enough liquid reagent (less than 50mL in each half-cell) tomake sure that there is sufficient electrical contact between them.It does not matter which half-cell is in the porous pot and whichhalf-cell is in the plastic beaker. Change the solutions for eachgalvanic cell, even if the same solution is used for two subsequentcells.
1)Zn|Zn2+(0.100M)||Pb2+(0.100M)|Pb
2)Zn|Zn2+(0.100M)||Fe2+(0.100M)|Fe
3)Pb|Pb2+(0.100M)||Cu2+(0.100M)|Cu
4)Fe|Fe2+(0.100M)||Cu2+(0.100M)|Cu
5) Cu|Cu2+(0.100M)||Fe3+(0.0500M), Fe2+(0.0500M)|C
6) Zn|Zn2+(0.100M)||Fe3+(0.0500M), Fe2+(0.0500M)|C
7) Fe|Fe2+(0.100M)||Fe3+(0.0500M), Fe2+(0.0500M)|C
