Question

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 cell) or running an electrolytic experiment (which includes recharging a battery) involves drawing or imposing a current on the system - thus moving away from steady state in one direction or the other. Predict what will happen to the magnitude of observed cell potential (will it increase stay the same, or decrease) in each of the following cases: (a) using battery: (6) electrolysis, e.g. electrogalvanizing.
