why sodium metal cannot be extracted from the electrolysis of aqueous sodium chloride solution?specify the details
Asked by | 16 Aug, 2012, 07:19: PM
Expert Answer
Because hydrogen has a lower discharge potential than sodium.
If it forms in aqueous solution it would immediately react with the water and produce NaOH.
Sodium is extracted by electrolysis (in the Downs Cell) of molten sodium chloride (in the presence of calcium chloride to ensure the mixture stays molten at a lower temperature.)
