Industrial uses Hall-Heroult process for producing aluminiumProduction of aluminium, lithium, sodium, potassium, magnesium Coulometric techniques can be used to determine the amount of matter transformed during electrolysis by measuring the amount of electricity required to perform the electrolysis Production of chlorine and sodium hydroxide Production of sodium chlorate and potassium chlorate Production of perfluorinated organic compounds such as trifluoroacetic acid Production of electrolytic copper as a cathode, from refined copper of lower purity as an anode.
In chemistry and manufacturing, electrolysis is a method of using a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially highly important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.
According to second law of electrolysis when the same quantity of
electronic current is passed through solutions of salts of two different
cells, the amounts of the metals deposited on the cathodes of the two
cells are proportional to their equivalent masses of the respective
metals. If the amounts of the metals deposited on the cathodes be WA and WB respectively, then
Electrolysis has wide applications in industries. Some of the important applications are, as follows,
(i) Production of hydrogen by electrolysis of water.
(ii) Manufacture of heavy water .
(iii) The metals like K, Mg, Al, etc., are obtained by electrolysis of fused electrolytes.
(iv) Non-metals like hydrogen, fluorine, chlorine are obtained by electrolysis.
(v) In this method pure metal is deposited at cathode from a solution containing the metal ions etc.
