Question

4. Write down steps of electrolysis for
(1) molten lead bromide and
(ii) aqueous solution of magnesium chloride
Also mention the products formed at cathode and anode.​

Answer 1

Answer:

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.
