The electrolysis of molten sodium chloride to obtain chlorine and sodium, which can be further processed to produce sodium hydroxide, is an important industrial-scale process. The experiment depicted here can be used for a simple demonstration of the important steps in this process. Due to the high melting point of sodium chloride, however, lower-melting lead chloride is used as the raw material in the model experiment.
