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.
Explanation:
6. Thus, electrolysis of lead (II) bromide produces lead and bromine gas.
