Question
**Electrochemical Cell Notation and Calculation**

In this example, we analyze an electrochemical cell comprising different elements and compounds at a given temperature.

**Cell Notation:**

\[ \text{Pt (s)} \mid \text{H}_2 \text{(g)} \mid \text{H}^+ \text{(aq)} \parallel \text{Pb}^{2+} \text{(aq)} \mid \text{Pb (s)} \]

**Details:**

- **Pt (s):** Platinum solid, serving as an inert electrode.
- **H2 (g):** Gaseous hydrogen.
- **H+ (aq):** Aqueous hydrogen ions. (1M concentration is indicated)
- **Pb2+ (aq):** Aqueous lead ions.
- **Pb (s):** Solid lead.

**Conditions:**

- **Temperature:** 25°C

**Query:**

- The task is to determine the pH of the solution, expressed as the concentration of hydrogen ions \([H^+]\).

**Note on Diagram/Graph:**

There are no diagrams or graphs present in the material, only textual chemical notation and labels indicating concentrations.
