Question
**Electrochemical Cell Notation**

**Task:** Write the cell notation for an electrochemical cell consisting of an anode where Cr(s) is oxidized to Cr³⁺(aq) and a cathode where H⁺(aq) is reduced to H₂(g) at a platinum electrode. Assume all aqueous solutions have a concentration of 1 mol/L and gases have a pressure of 1 bar.

**Solution Box:**
__[Solution not provided]__

**Explanation:**
- **Anode Reaction:** Cr(s) → Cr³⁺(aq) + 3e⁻
  - Chromium solid is oxidized, losing electrons.
  
- **Cathode Reaction:** 2H⁺(aq) + 2e⁻ → H₂(g)
  - Hydrogen ions are reduced to form hydrogen gas.

- **Overall Cell Notation:**
  - Represented as Cr(s) | Cr³⁺(aq) || H⁺(aq) | H₂(g) | Pt

Where:
- "|" denotes a phase boundary.
- "||" denotes the salt bridge or junction between the two half-cells. 
- "Pt" indicates the platinum electrode used in the hydrogen electrode part of the cell.

**Conditions Assumed:**
- Concentration of aqueous solutions = 1 mol/L
- Pressure of gases = 1 bar
