What is the color of chlorine (Cl2) and its typical odor description?

Chlorine (Cl2) is indeed recognized for its greenish-yellow color, which is distinct and easily identifiable. This coloration is important in safety contexts, as it helps to alert individuals to its presence in the environment. The strong bleach odor associated with chlorine is also a defining characteristic. This odor is reminiscent of household bleach, which is a diluted form of chlorine, making it recognizable to many people.

The combination of its color and odor is essential for awareness and safety, particularly in situations where chlorine gas may be present, such as in swimming pools or certain chemical manufacturing areas. Understanding these properties is crucial for recognizing the potential hazards of chlorine and taking appropriate precautions to avoid exposure.
