Principle

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.
