    can be separated by electrolysis. This method is used for the extraction of some metals from their ore. See for example lead bromide, magnesium chloride, potassium chloride, sodium chloride and zinc chloride. The situation is more complicated when the substance used for electrolysis is dissolved in water. Electrolysis can also be used for metal plating.
