Redox and electrochemistry > electrolysis

This experiment demonstrates that conduction is only possible where lead(II) bromide is molten, and that metallic lead and bromine are the products of electrolysis of the molten electrolyte. This is a demonstration that can be done as an introduction to studying electrolysis.
 

This demonstration is designed to find the value of the Faraday constant – the amount of electric charge carried by one mole of electrons - from the electrolysis of aqueous copper(II) sulfate solution, using weighed copper electrodes.
