Electrolysis of molten ionic compounds

• Lead ions will be attracted towards the cathode

  Bromide ions will be attracted towards the anode.

  A)

  B)

  
• Each Pb2+ ion will gain 2 electrons to form solid Pb

  Lead is observed as a grey metal on the cathode

  Each Br- ion will lose one electron to form Br gas

  Bubbles will be observed at the anode

  A)

  B)

  
• Electrons are lost at the anode and gained at the cathode
