Question
**Writing the Cell Diagram for the Given Electrochemical Cell**

The diagram illustrates a galvanic (voltaic) cell, consisting of two half-cells connected by a salt bridge. The components of this electrochemical cell are detailed below:

### Components:

- **Left Half-Cell:**
  - **Electrode:** A platinum (Pt) electrode, used as an inert conductor.
  - **Solutions/Compounds:**
    - Potassium chloride (\(\text{KCl(aq)}\)) is the electrolyte.
    - Mercurous chloride (\(\text{Hg}_2\text{Cl}_2(s)\)) is a solid.
    - Elemental mercury (\(\text{Hg(l)}\)), which is in liquid form.

- **Right Half-Cell:**
  - **Electrode:** Zinc (\(\text{Zn}\)) metal.
  - **Solution:** Zinc chloride (\(\text{ZnCl}_2(aq)\)) serving as the electrolyte.

### Connections:
- An external circuit connects the two electrodes shown by the wires leading from the \(-\) terminal (left) to the \(+\) terminal (right) through a voltmeter (V), allowing electron flow.
- A salt bridge is included between the two solutions to maintain electrical neutrality by allowing the migration of ions.

### Cell Diagram:
The cell diagram, representing the reaction occurring in the galvanic cell, is written as follows:

\[
\text{Pt} | \text{Hg}_2\text{Cl}_2(\text{s}) | \text{Hg}(\text{l}) || \text{ZnCl}_2(\text{aq}) | \text{Zn}
\]

**Explanation:**
- The single vertical lines (\(|\)) represent phase boundaries. 
- The double vertical line (\(||\)) signifies the salt bridge separating the two half-cells.
- The left side denotes the anode side (oxidation occurs, \(-\) electrode).
- The right side denotes the cathode side (reduction occurs, \(+\) electrode).

This cell generates electrical energy through a spontaneous redox reaction, which can be measured with the voltmeter in the circuit. Using a diagrammatic representation such as this is crucial for visualizing the components and reactions of galvanic cells in electrochemistry.
