What do you think would happen if you ran an electric current through a glass of water? If you set it up just right, you might see bubbles of gas rising to the surface. What is happening inside the water to make the bubbles? It's a process called electrolysis that uses electricity to separate chemical compounds. Inside the glass of water, water molecules are being split to produce hydrogen and oxygen gas, which bubbles to the surface. The word electrolysis comes from the Greek lysis which means 'to dissolve' or 'break apart.'
Electrometallurgy is the process of reduction of metals from metallic compounds to obtain the pure form of metal using electrolysis. Aluminium, lithium, sodium, potassium, magnesium, calcium, and in some cases copper, are produced in this way.
Production of chlorine and sodium hydroxide
Production of sodium chlorate and potassium chlorate
Production of perfluorinated organic compounds such as trifluoroacetic acid by the process of electrofluorination
Production of electrolytic copper as a cathode, from refined copper of lower purity as an anode.
Electrolysis has many other uses:
Production of oxygen for spacecraft and nuclear submarines.
Production of hydrogen for fuel, using a cheap source of electrical energy.
Electrolysis is also used in the cleaning and preservation of old artifacts. Because the process separates the non-metallic particles from the metallic ones, it is very useful for cleaning a wide variety of metallic objects, from old coins to even larger objects including rusted cast iron cylinder blocks and heads when rebuilding automobile engines. Rust removal from small iron or steel objects by electrolysis can be done in a home workshop using simple materials such as a plastic bucket, tap water, lengths of rebar, washing soda, baling wire, and a battery charger.[4]
