WebMolten lead bromide, PbBr2(l), is an electrolyte. During electrolysis: Pb2+ ions gain electrons at the cathode and become Pb atoms Br- ions lose electrons at the anode and become Br atoms,... Web1) Bauxite is impure aluminium oxide, Al 2O 3. The impurities are iron oxides, silicon dioxide and titanium dioxide. Bauxite is the major aluminium ore. 2) The first step is to purify the bauxite to get pure aluminium oxide, Al 2O 3. 3) Molten aluminium oxide is electrolysed in a solution of cryolite, Na 3AlF 6 to give out the required ...
WebElectrolysis is not possible with solid lead (II) bromide. This is because the ions are held in a three-dimensional lattice, unable to move freely to the electrodes. Melting enables the ions to become mobile and to travel to the respective electrodes. At the cathode (-) molten lead is formed: Pb 2+ (l) + 2e - → Pb (l) WebElectrolysis of sodium chloride solution (brine) As shown above, the electrolysis of sodium chloride solution will produce chlorine gas at the anode and hydrogen gas at the …
