Reference: AQA
At the cathode, hydrogen is produced if the metal is more reactive than hydrogen; at the anode, oxygen is produced unless halide ions are present, in which case the halogen is produced.
At the cathode, hydrogen is usually formed unless the metal is less reactive than hydrogen, when the metal is deposited.
