electrolysis of molten lead bromide products electrode
· (a) The negative cathode electrode reaction for the electrolysis of molten lead(II) bromide. The positive lead(II) ions are attracted to the negative electrode and are discharged to form molten lead. Pb 2 (l) 2e==> Pb (l) positive ion reduction by electron gain. This is a reduction reaction because the lead ions gain electrons.
