Where will chlorine gas accumulate if a leak occurs?

At the top of the tank
Near the bottom of the tank
In the middle of the tank
Outside the tank

The correct answer is: Near the bottom of the tank

Chlorine gas is denser than air, which means that if a leak occurs, the gas will tend to accumulate closer to the ground rather than rising. This characteristic is crucial for recognizing the potential hazards associated with chlorine gas leaks. The accumulation near the bottom of the tank is a result of the weight of chlorine gas compared to the environment, leading to the potential for dangerous concentrations at lower levels. Understanding the behavior of chlorine gas when released is essential for safety measures, emergency response, and effective ventilation strategies in areas where chlorine gas is stored or used.
