How to Make Sodium


Isolation of sodium</a>

Sodium is a very active alkali metal.

It is rapidly oxidized in air, often with ignition, it reacts vigorously with water, releasing hydrogen fuel and forming a solution of caustic soda.

It is for this reason that it can not be found inIn its pure form, sodium is found in compounds. In industry, sodium is produced by the complex electrochemical processes to which molten sodium salts are exposed.

But a small amount of this marvelous metal can be obtained by an artisanal method.

You will need

  • Graphite cup, graphite rod, sodium hydroxide, oil, powerful constant current source.



Take a cup made of graphite (ideal is a cup of noble metal). Place in it a small piece of sodium hydroxide (caustic soda), it should be slightly moistened.


Then round a piece of sodium hydroxide pourA little dehydrated oil, but so that the top of the piece is not covered by it. After that, take a powerful source of direct current and connect its negative wire to the cup, and connect the positive lead to the graphite rod.


Now turn on the power, and immerse the rod in theMoistened sodium hydroxide. The moisture present in the material will increase the electrical conductivity, but it will not be enough to completely react with sodium. At high current power, metallic sodium will be released on the minus electrode (graphite cup), and the oil layer will prevent it from contacting the air.
