This forms a galvanic (voltaic) cell (battery).
The voltage of a galvanic cell made with magnesium (Mg) and gold (Au) can be calculated using their standard reduction potentials. Magnesium has a standard reduction potential of about -2.37 V, while gold has a standard reduction potential of +1.50 V. The overall cell potential can be calculated by subtracting the reduction potential of magnesium from that of gold, resulting in a voltage of approximately +3.87 V. This indicates that the galvanic cell can produce a significant amount of electrical energy.

The standard cell notation for a galvanic cell with aluminum and gold electrodes is represented as: Al(s) | Al³⁺(aq) || Au³⁺(aq) | Au(s). In this notation, the anode (aluminum) is listed on the left, and the cathode (gold) is on the right. The double vertical line (||) indicates the salt bridge or separation between the two half-cells. The state of each component (solid or aqueous) is also noted.

aluminum oxidized, zinc reduced
The standard cell notation for a galvanic cell made with zinc and aluminum is represented as: Zn(s) | Zn²⁺(aq) || Al³⁺(aq) | Al(s). In this notation, the anode (zinc) is listed on the left, followed by its ion in solution, then the double vertical line representing the salt bridge, and finally the cathode (aluminum) and its ion in solution. This format clearly indicates the direction of electron flow from zinc to aluminum.
