The aluminum metals
In an electrolytic cell
A still cell refers to a type of electrolytic cell used for producing chlorine gas and caustic soda (sodium hydroxide) through the electrolysis of brine (sodium chloride solution). It is characterized by its stationary or non-moving electrodes and typically operates at lower temperatures compared to other types of electrolytic cells.
In an electrolytic cell with aluminum and gold electrodes, aluminum would be oxidized at the anode. This is because aluminum has a higher tendency to lose electrons compared to gold, making it more likely to undergo oxidation.

At the cathode of the electrolytic cell with zinc and aluminum electrodes, the reduction of aluminum ions into aluminum metal will occur. Aluminum ions gain electrons to form solid aluminum metal, while zinc remains unchanged as it does not participate in the reaction at the cathode.
the gold metal
In an electrolytic cell with nickel and copper electrodes, nickel at the anode gets oxidized, losing electrons to form nickel ions. The copper electrode at the cathode gains electrons and gets reduced, forming copper metal. This process allows for the transfer of nickel ions from the anode to the cathode.
