Suggest a list of metals that are extracted electrolytically.
The metals that are extracted electrolytically include Sodium (Na), Magnesium (Mg), and Aluminium (Al). These metals are produced on a large scale by electrochemical reduction of their respective cations where no suitable chemical reducing agents are available for this purpose.
Sodium and magnesium metals are produced by the electrolysis of their fused chlorides. Aluminium is produced by electrolysis of aluminium oxide in the presence of cryolite.
Explanation
The textbook context explicitly mentions in section 2.29 that 'Many metals like Na, Mg, Al, etc. are produced on large scale by electrochemical reduction of their respective cations where no suitable chemical reducing agents are available for this purpose.' It further specifies that sodium and magnesium are produced by electrolysis of fused chlorides, while aluminium is produced by electrolysis of aluminium oxide with cryolite. Note that copper mentioned in the context refers to purification (refining) of impure copper, not primary extraction.
