Electrolysis of molten Lead (II) Bromide using inert graphite electrodes.

Electrolysis is a process where you use electrical energy (electricity) to make a chemical reaction happen that wouldn't happen otherwise. Electrolysis is often used to break a chemical compound down into the elements that make it up. Here, we'll look at the electrolysis of water into hydrogen and oxygen, and the electrolysis of sodium chloride into sodium and chlorine. In electrolysis, electrons get pushed by a battery into the cathode (the site of reduction), and they get pulled by a battery from the anode (the side of oxidation).

Mr. Scullion discusses solution electrolysis of concentrated aqueous sodium chloride (brine) using inert graphite electrodes. The electrolysis of brine is shown and discussed fully in this short video. You will see how chlorine is produced at the anode and hydrogen at the cathode.
