Extraction of Sodium. As sodium is a highly electro positive metal it cannot be prepared by the usual methods of reduction. The metal is extracted by the electrolysis of a molten mixture of NaCl, CaCl 2 and KF in a Downs cell at 600 degree Celsius. The cell has a graphite anode and a circular iron cathode, both covered and with proper outlets
Making Sodium Metal - Sodium Extraction: NOTE: See my previous video, 'Making Sodium Metal' to see how I make sodium in the first place. The reaction is as follows: 2Mg + 2NaOH = 2MgO + 2Na + H2 This is my new process of reacting NaOH and Mg in a water cooled soup can for creating elemen

Extraction of Sodium The two methods used for extracting sodium metals are, * Castner's process: By the electrolysis of fused caustic soda. * Down's process: By the electrolysis of fused sodium chloride. Castner's process Molten sodium hydroxide (caustic soda, NaOH) is electrolyzed using an iron cathode and nickel anode

During electrolysis, an aqueous solution of sodium chloride is never used. The water present in the solution leads to the formation of sodium hydroxide in the solution and so…sodium metal isn't obtained. It defeats the purpose.
