The electrolysis of molten sodium chloride to obtain chlorine and sodium, which can be used to produce sodium hydroxide, is an important industrial-scale process. The experiment is a simple demonstration of the important steps in this process. Due to the high melting point of sodium chloride, lead chloride (with a lower melting point) is used as starting material in the model experiment (instead of sodium chloride)

Benefits

Easy and fast experiment set-up
Impressive demonstration how to produce alkali metals like sodium

Tasks

Demonstration the electrolysis of molten sodium chloride to obtain chlorine and sodium.

Learning objectives

Electrolysis
Fused-salt electrolysis
Preparation of Chlorine and sodium
