Chlorine gas is how much denser than air?

Chlorine gas is indeed approximately 2.5 times denser than air. The density of chlorine gas is about 3.2 grams per liter, while the density of air is around 1.3 grams per liter. This significant difference means that chlorine gas will not rise and disperse into the atmosphere as lighter gases would; instead, it tends to stay lower in the air, which can lead to hazardous situations in confined spaces or low-lying areas.

Understanding the density of chlorine gas is crucial for safe handling and emergency response. For example, if a leak occurs, responders need to be aware of this density characteristic to effectively plan ventilation and evacuation. Overall, recognizing the density of chlorine gas relative to air is essential for water operators and those working with chlorine in various applications.
