WebWhat are the products when molten lead bromide is Electrolysed? Molten lead bromide, PbBr 2 (l), is an electrolyte. During electrolysis: Pb 2 + ions gain electrons at the cathode and become Pb atoms. Br – ions lose electrons at the anode and become Br atoms, which pair up to form Br 2 molecules.
