4. Use the chemical equation for the redox reaction and the Nernst equation to explain the following: a. A battery using the cell "CdCd (1.5M)||Ni?(1.5M)Ni" would eventually die "its potential would get too low to power a device") even though neither the Cd nor the N? is completely gone. b. Would you expect a battery using the cell Zn|Zn2+||Fe Fe?*|Pt to last longer than the cell in part a?

Use the Nernst equation to calculate the concentration of the unknown solution. Base this on your experimental voltage of 0.4410 V for the galvanic cell with silver combined with your copper half-cell. Use the unrounded [Cu2+] value of 0.04969 M and the unrounded value of the constants. E(cell) = 0.462 V Ag+ + e- → Ag(s) E(knot)= 0.799V Cu2+ + 2e- → Cu(s) E(knot)=0.337V

4. A practical galvanic cell is colloquially known as a "battery". Is Faraday's law in any way applicable to using a battery (hence a galvanic cell)? If so, how? (Hint: Did you see the waterfall or water + gravity analogy in the tutorial? Difference in height is not the only important waterfall parameter). 5. Ideally, determination of cell emf is a steady-state experiment with no net change in concentrations of ions and no current flowing. However, using a battery (galvanic...
