Explanation
During the electrolysis of a molten ionic compound, metal ions gain electrons at the cathode to form a metal.
Common mistake
Metal Formation at the Cathode
Students often think that a metal is always produced at the cathode, regardless of the ionic compound being electrolysed.
Students should remember that a metal forms at the cathode only when a molten ionic compound is electrolysed, and they should consider the specific ions present in the compound.
