WebDec 4, 2024 · Answer: Molten lead bromide (PbBr 2) forms and Br – ions. The positive lead ions (Pb 2) move to the cathode, and gain two electrons and change into lead atom. Pb 2+ + 2e – Pb (Lead) Lead is deposited at the cathode. The negative bromide ion migrates to the anode. It loses an electron and becomes a bromide atom. WebVideo transcript. - [Voiceover] Before we get into electrolysis, let's review the structure of a voltaic cell so we can compare it to an electrolytic cell. So a voltaic cell uses a spontaneous redox reaction to produce an electric current. So if we started our zinc electrode, solid zinc turns into zinc two plus ions. somewhere over the rainbow wedding song https://segecologia.com
