What would be at the Cathode and Anode for: -Lead Iodide [PbI²] -Potassium Chloride [KCl] -Aluminium Oxide [Al²O³] Also give the Half Equations for each Element

Lead Iodide: -Lead would be at Cathode [Pb²+ + 2e- --->Pb] -Iodine would be at Anode [2I- ---> I² + 2e-] Potassium Chloride -Potassium would be at Cathode [K+ + e- -->K] -Chloride would be at Anode [2Cl- ---> Cl² + 2e-] [Chlorine Gas] Aluminium Oxide: -Aluminium would be Cathode [Al³+ + 3e- ---> Al] -Oxygen would be at Anode [2O²- ---> O² + 4e-]
