Transcribed Image Text:**Problem Statement:**
Calculate the cell potential for the following galvanic cell at 25°C:
Al(s) | Al<sup>3+</sup> (0.0632 M) || Au<sup>3+</sup> (0.255 M) | Au(s)
---
**Explanation:**
This problem involves determining the cell potential of a galvanic (voltaic) cell at 25°C. The cell is composed of an aluminum electrode and a gold electrode. The aluminum metal dissolves into an aluminum ion solution, while gold ions are reduced to solid gold.
**Key Components:**
- **Anode Reaction:** Al(s) → Al<sup>3+</sup> + 3e<sup>-</sup>
- **Cathode Reaction:** Au<sup>3+</sup> + 3e<sup>-</sup> → Au(s)
**Concentration of Ions:**
- Al<sup>3+</sup>: 0.0632 M
- Au<sup>3+</sup>: 0.255 M
Using the Nernst equation or the standard electrode potential values, the cell potential can be calculated.
