Answer
Negative electrode
Explanation
The cathode is the negative electrode where reduction occurs, and positive ions gain electrons.
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.
