are produced on 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 and aluminium is produced by electrolysis of
aluminium oxide in presence of cryolite Quantitative Aspects of Electrolysis
Michael Faraday was the first scientist who described the quantitative
aspects of electrolysis Now Faraday’s laws also flow from what has
been discussed earlier
