A conductor is a material that can conduct electric current without undergoing chemical change.
Ionic compounds in solid state are non-electrolytes.
Active electrodes do not participate in the electrolysis reaction.
In molten electrolysis, cations move to the cathode and anions move to the anode.
In the extraction process of aluminum, oxygen is produced at the cathode.
Aluminum is produced at the anode in the aluminum extraction process.
Reactive metals like magnesium can be extracted by reduction with carbon.
Zinc is used as a sacrificial agent in the galvanization process.
Aluminum forms a hard oxide layer that protects it from further corrosion.
Rusting only occurs on iron.
Iron is more electropositive than magnesium.
A more electropositive metal will corrode more easily in air.
Rusting of iron requires the presence of oxygen and water.
The best method to prevent rusting is by painting the surface of iron.
Galvanization is a method of coating using zinc.
