Electrolysis of lead (II) bromide

Référence de la vidéo 11939324
Electrolysis of lead (II) bromide. Footage of electrodes (upper left) suspended in a crucible containing lead (II) bromide. Electrical power will be provided by the power pack at right, though this is not yet switched on. The bunsen burner is used to heat the crucible and turn the lead (II) bromide molten. In its molten state, it will conduct electricity and the light bulb next to the electrodes will come on, indicating that electrical current is flowing through the molten chemical. Electrolysis of ionic solutions or ionic melts causes the ions to be deposited at electrodes of the opposite polarity. In this case, the negative bromide ions are deposited at the anode, forming bromine gas (Br2). Molten lead (Pb) is deposited at the cathode. For clips showing stages in this electrolysis, see K004/5371 to K004/5374.
