WebDuring electrolysis, at the cathode (negative electrode), positively charged ions gain electrons and so the reactions are reductions. At the anode (positive electrode), … Balance the half equation for the formation of aluminium during electrolysis: Al3++ e-→ Al. The balanced half equation is: Al3++ 3e-→ Al (because three negatively charged electrons are needed to balance the three positive charges on the aluminium ion). Question 1. Write a balanced half equation for the … Meer weergeven Positively charged ions gain electrons at the cathode. These are half equations for some reactions at the cathode: Na++ e-→ Na Pb2++ 2e-→ Pb 2H++ 2e-→ H2 Meer weergeven Negatively charged ions lose electrons at the anode.
