- Electrodes: Zinc electrodes
- Electrolyte: molten sodium iodide
I know that at the cathode, sodium metal will be formed because only sodium ions are present for reduction.
At the anode, originally iodine should be formed with inert electrodes such as graphite. However, since zinc electrodes are used, and zinc metal is a stronger reducing agent than iodide, hence zinc should be oxidised into zinc ions.
My question is: what will be the reaction occurring at the anode? Will zinc ions or iodine be formed? Or is this case of electrolysis even possible?
