How can chlorine leaks be detected?

1. Using litmus paper

2. Pressure meter readings

3. Ammonia solution with Q-Tip

4. Color change indicator

The correct answer is: Ammonia solution with Q-Tip

Chlorine leaks can be detected effectively using ammonia solution with a Q-Tip. When ammonia gas comes into contact with chlorine gas, a chemical reaction occurs, resulting in the formation of a white cloud of ammonium chloride. This reaction is highly visible and provides a straightforward visual indication of a chlorine leak. This method is widely used in practice because it allows for a quick and immediate response to potential leaks, helping to safeguard workers and the environment from the harmful effects of chlorine exposure. While other methods might have limited efficacy or specificity in detecting chlorine, using ammonia solution offers a reliable and unmistakable signal of chlorine presence. The other options—such as litmus paper, pressure meter readings, and color change indicators—may not effectively identify chlorine leaks specifically or might not provide instant or accurate results when it comes to detecting gaseous chlorine. Thus, using an ammonia solution with a Q-Tip stands out as the most suitable detection method.
