the gold metal
The answer is not c.
In an electrolyte cell with aluminum and gold electrodes, oxidation occurs at the aluminum electrode. Aluminum, being more reactive than gold, donates electrons and is oxidized to form aluminum ions (Al³⁺). The gold electrode, on the other hand, typically acts as the cathode, where reduction occurs as it accepts the electrons released from the aluminum. This movement of electrons generates an electric current in the electrolyte cell.

The aluminum metals
Electrolysis in an electrolytic cell can be identified by observing the production of gas bubbles at the electrodes, indicating a chemical reaction is occurring. Additionally, changes in the color of the electrolyte solution or the deposition of solid material on the electrodes can also signal electrolysis. A measurable change in voltage or current can further confirm that the process is taking place.
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.

The answer is not c.
In an electrolytic cell, oxidation occurs at the anode and reduction at the cathode. For the given metals, aluminum (Al) is oxidized, losing electrons, while silver (Ag) and zinc (Zn) are reduced, gaining electrons. Thus, in the context of an electrolytic cell, Al and Li are oxidized, whereas Au, Zn, and Fe can be reduced depending on the specific half-reactions involved.

The standard cell notation for an electrolytic cell with aluminum and gold electrodes can be represented as follows: Al(s) | Al³⁺(aq) || Au³⁺(aq) | Au(s). In this notation, the aluminum electrode is the anode where oxidation occurs, while the gold electrode is the cathode where reduction takes place. The double vertical line (||) indicates the salt bridge separating the two half-cells.
