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 Faraday’s Laws of Electrolysis
After his extensive investigations on electrolysis of solutions and melts
of electrolytes, Faraday published his results during 1833-34 in the
form of the following well known Faraday’s two laws of electrolysis:
(i) First Law: The amount of chemical reaction which occurs at any
electrode during electrolysis by a current is proportional to the
quantity of electricity passed through the electrolyte (solution or
melt)
