What is true about chlorine gas?

• A. Chlorine gas is 2.5 times heavier than air.
• B. Chlorine gas is 2.5 times lighter than air
• C. Chlorine gas is 5 times heavier than air
• D. Chlorine gas is 5 times lighter than air

Answer: (A)

Chlorine gas has a molecular weight of approximately 35.5 g/mol, whereas the average molecular weight of air is about 29 g/mol. When you compare these two values, you'll find that chlorine gas is indeed heavier than air. Specifically, it is about 2.5 times heavier than air, which is why the correct statement is that chlorine gas is 2.5 times heavier than air. This property of chlorine has significant implications for safety and handling, as it tends to settle in low-lying areas. Understanding the density of chlorine in relation to air is critical for operators working with this chemical in water treatment and distribution systems, as it influences ventilation, exposure risks, and emergency response strategies.
