why graphite ( carbon ) rods are used as electrodes in …
2011/9/15· Carbon - the most important reason is that graphite conducts electricity! As for LiCl, it will conduct as it cools down to the freezing (melting) point. If it conducts after that, it is because lithium metal is now short-circuiting the electrodes.
electrolysis of molten lead bromide products electrode …
The electricity must flow through electrodes dipped into the electrolyte to complete the electrical circuit with the battery. Electrolysis can only happen when the circuit is complete, and an electrical current (electricity) is flowing, then the products of electrolysing molten lead(II) bromide are released on the electrode surfaces where they can be collected.

Why does metal and graphite conduct electricity in …
2009/4/23· For a substance to conduct electricity, it must contain freely moving charged particles - either electrons or ions - that can carry the charge of the electric current through the substance. In both graphite and metal there are ''delocalised'' electrons that are not firmly bound to any particular atom and are free to move about within the substance, carrying the current
