a. Suggest a suitable substance from which inert electrodes can be made.
b. Give half-equations for the reactions at both electrodes.
c. How will the concentration of the copper(II) nitrate solution change over time?
d. What will happen to the pH of the electrolyte as electrolysis proceeds?
e. Describe what would be observed as electrolysis proceeds.
