Zn(s)/Zn2+(aq)//Au+(aq)/Au(s)
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.
Mg(s) | Mg2+(aq) Au+(aq) | Au(s)
Zn(s)/Zn2+(aq)//Au+(aq)/Au(s)
Zn(s)/Zn2+(aq)//Au+(aq)/Au(s)
Type your answer here... Al(s) | Al3+(aq) Mg2+ (aq) | Mg(s)
Al(s) I AI3+(aq) II AI3+ (aq) I Al(s)
Zn(s)/Zn2+(aq)//Au+(aq)/Au(s)
Zn(s)/Zn2+(aq)//Au+(aq)/Au(s)
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.
