4. The cell potentials of many oxidation-reduction reactions are highly dependent on pH. Consider the following equation: 3 Co(s) + 2NO3(aq) + 8 H+ (aq) -----> 3 Co2+ (aq) + 2NO(g) + 4H₂O(1) a) Determine the standard cell potential for the reaction. b) What would be the pH of the solution at standard conditions? (HINT: What are the concentrations of all aqueous species at standard conditions?) c) Determine the cell potential for the reaction at a pH of_2.0. (Hint: You will need to use the Nernst equation.) Assume that all concentrations, other than that of H*, are standard. d) Based on your answers above, would you say that the reaction is more favorable (i.e., more spontaneous) at higher pH or lower pH? Explain.

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
