Chlorine gas has what effect on air density?

Chlorine gas is denser than the air we breathe, which primarily consists of nitrogen and oxygen. The molecular weight of chlorine (approximately 35.45 g/mol) is significantly higher than that of air, which averages around 29 g/mol. This higher density means that in an environment where chlorine is present, it will tend to sink and accumulate at lower levels, potentially creating hazardous conditions in confined spaces.

This characteristic is critical in water distribution and treatment facilities where chlorine is used for disinfection. Understanding the density of chlorine gas is essential for safety protocols, ensuring adequate ventilation, and implementing proper chemical handling procedures.
