The process is useful in many industrial processes. 9-V Pencil lead Example: The electrolysis of molten lead bromide (PbBr 2). Add two graphite rods as the electrodes and connect this to a power pack or battery. During electrolysis, the O 2 ion leaves the cathode, diffuses through the molten salt, and is discharged to CO 2 on the graphite anode. This is a reduction reaction This electrolysis contradicts what I learned, as lead is . Lead bromide dissociates to form P b 2 + ions are discharged at the cathode as neutral lead atoms by accepting electrons whereas B r ions are discharged at the anode as neutral bromine atoms by giving up electrons. because the lead ions gain electrons. All copyrights reserved on revision notes, images, of electrons (i) molten electrons (oxidation) to form gcsescience.com During the experiment highly toxic bromine vapour is produced. [1] (iv) State the name of the products formed during this electrolysis; . The electrolysis reactions will be carried out in a electrolytic cell consisting of a Petri dish, a 9-V battery, and carbon (pencil lead) electrodes (Figure 1). Two bromine atoms then combine and the diatomic bromine gas is released at the anode. The negative terminal is attached to one rod, which becomes the negative electrode, the cathode. Solution (2016) (a) Electrostatic forces of attraction between ions in the solid state are very strong. The explosions occurring at one electrode during electrolysis.
