State true or false
The conductivity of molten `KCl` is due to the movement of `K^(o+)` and `Cl^(c-)` ions.

Answer

To determine whether the statement "The conductivity of molten KCl is due to the movement of K^(o+) and Cl^(c-)" is true or false, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding Molten KCl**:
- Molten KCl refers to potassium chloride that has been heated until it becomes a liquid. In this state, the ionic bonds in KCl are broken, allowing the ions to move freely.

2. **Identifying the Ions Present**:
- In molten KCl, the compound dissociates into its constituent ions: K^+ (potassium ions) and Cl^- (chloride ions).

3. **Role of Ions in Conductivity**:
- Conductivity in a substance is primarily due to the movement of charged particles. In the case of molten KCl, the movement of K^+ and Cl^- ions allows the substance to conduct electricity.

4. **Conclusion**:
- Since the conductivity of molten KCl is indeed due to the movement of K^+ and Cl^- ions, the statement is true.

### Final Answer:
The statement is **True**.
