**Balancing Redox Reactions in Acidic Solutions**

**Problem:**

Balance the following redox reaction in acidic solution:

\[ \text{ClO}_3^- (\text{aq}) + \text{Cl}^- (\text{aq}) \rightarrow \text{Cl}_2 (\text{aq}) \]

**Explanation:**

In redox reactions, the number of electrons lost in oxidation must equal the number of electrons gained in reduction. Here’s how to balance this reaction in an acidic solution:

1. **Separate the reaction into two half-reactions:**

   - **Reduction Half-Reaction:**
     \[ \text{ClO}_3^- \rightarrow \text{Cl}_2 \]

   - **Oxidation Half-Reaction:**
     \[ \text{Cl}^- \rightarrow \text{Cl}_2 \]

2. **Balance each half-reaction for mass and charge:**

   - **Reduction Half-Reaction:**
     Identify the oxidation state changes and balance electrons.
     \[ \text{ClO}_3^- + 6\text{H}^+ + 6\text{e}^- \rightarrow \text{Cl}_2 + 3\text{H}_2\text{O} \]

   - **Oxidation Half-Reaction:**
     \[ 2\text{Cl}^- \rightarrow \text{Cl}_2 + 2\text{e}^- \]

3. **Combine the balanced half-reactions:**

   Ensure that the electrons cancel each other out. Multiply the oxidation half-reaction by 3 and add to the reduction half-reaction:
   \[
   \begin{align*}
   &\text{Reduction: } \text{ClO}_3^- + 6\text{H}^+ + 6\text{e}^- \rightarrow \text{Cl}_2 + 3\text{H}_2\text{O} \\
   &\text{Oxidation: } 6\text{Cl}^- \rightarrow 3\text{Cl}_2 + 6\text{e}^- \\
   &\text{Overall: } \text{ClO}_3^- + 6\text{Cl}^- + 6\text{H}^+ \rightarrow 3\text{Cl}_2 +
