An electrolytic cell is set up. Two inert electrodes are attached to an external 6V battery, and are placed into a solution. The solution is a 1.00 M aqueous solution of calcium iodide (CaI2 (aq)). Determine which half-reactions are happening at the cathode and the anode of the electrolytic cell and explain your answer. My teacher uses half reaction with water to solve but I don't understand how you chose which water half reaction to use since there are three...
