WebElectrolysis of molten salts New substances form when a molten or dissolved ionic compound conducts electricity. For example, lead (II) bromide can be used to produce … WebElectrolysis is not possible with solid lead (II) bromide. This is because the ions are held in a three-dimensional lattice, unable to move freely to the electrodes. Melting enables the ions to become mobile and to travel to the respective electrodes. At the cathode (-) molten lead is formed: Pb 2+ (l) + 2e - → Pb (l) boys ballet costume
