Calculate the potential of a cell constructed with two nickel electrodes. The electrolyte in one compartment is 1.0 m Ni(NO3)2(aq). In the other compartment, NaOH has been added to a Ni(NO3)2 solution until the pH = 11.0 at 298 K. See Table 6I.1.

How do you determine which is the anode and which is the cathode?

usually the compartment with the lower concentration is the anode. This is because the lower concentration compartment would want more ions and in order to get more ions, it would have to donate electrons and oxidize the metal (Ni(s) --> Ni2+)

Return to “Appications of the Nernst Equation (e.g., Concentration Cells, Non-Standard Cell Potentials, Calculating Equilibrium Constants and pH)”
