Write True/False:
KCl can be use in salt bridge.

Answer

**Step-by-Step Solution:**

1. **Understanding Salt Bridge:**
- A salt bridge is used in electrochemical cells to maintain electrical neutrality by allowing the movement of ions between the two half-cells without mixing the solutions.

2. **Characteristics of Salt Bridge Compounds:**
- The compound used in a salt bridge should:
- Maintain neutrality in the cell.
- Allow the movement of ions from one solution to another.
- Not mix the two solutions.

3. **Analyzing KCl:**
- KCl (Potassium Chloride) dissociates into K⁺ (potassium ions) and Cl⁻ (chloride ions) in solution.
- Both K⁺ and Cl⁻ ions are of similar size and charge, which allows for effective ion movement.

4. **Conclusion:**
- Since KCl fulfills the necessary properties for a salt bridge, it can indeed be used in a salt bridge.

5. **Final Answer:**
- Therefore, the statement "KCl can be used in a salt bridge" is **True**.
