q 1 : Of the eight metals shown in Table 16-4, why did we first use copper as the reference electrode for each of the other metals?
q: 1 Using copper as the reference electrode, rank the cell voltage for each of the other anodes that you tested.
q: 3 Using the standard reduction potentials listed in Table 16-3, calculate the theoretical voltage for each of the cells you tested
and recorded in Table 16-4. How do the actual voltages you measured compare to the theoretical voltages you calculated? Propose an
explanation for any differences.
