How does chlorine gas compare to air in terms of weight?

• A. Lighter than air
• B. Heavier than air
• C. Equal to air
• D. None of the above

Answer: (B)

Chlorine gas is heavier than air. The molecular weight of chlorine is approximately 35.5 grams per mole, compared to the average molecular weight of air, which is about 29 grams per mole. This difference in density is significant; as a result, when chlorine gas is released into the atmosphere, it tends to accumulate closer to the ground instead of dispersing into the air. This property is important to consider in wastewater treatment processes and safety protocols since the accumulation of chlorine can pose risks, especially in confined spaces. Understanding the relative weight of gases is crucial for effective ventilation and gas handling procedures in wastewater facilities.
