5.5.3 Electrolysis of Molten lead (II) bromide
1. Figure above shows the apparatus set up for electrolysis of molten lead (II) bromide.
2. Lead (II) bromide powder in a crucible is heated.
3. The electrolysis process start when le an (II) bromide start melting.
4. At the Cathode
When electricity is flowing, a silvery deposit of lead metal forms on the cathode.
5. At the Anode
When electricity is flowing, brown fumes of bromine gas are seen at the anode.
6. Thus, electrolysis of lead (II) bromide produces lead and bromine gas.
