1.53 Describe experiments to investigate electrolysis, using inert electrodes, of molten salts such as lead(II) bromide and predict the products

Figure 1

• Set up the apparatus in figure 1
• The lead (metal) will be attracted to the negative cathode where it will gain electrons
• The bromine (non metal) will be attracted to the positive anode where it will lose electrons
• Lead and bromine formed
• Yay

Inert electrodes don't react with other substances - only play a role in electron transfer and you need to be able to draw that apparatus. Good luck, padawan.
