Final answer:
Ammonia vapors reacting with chlorine gas produce a white cloud of ammonium chloride, which can be used to detect chlorine leaks. Ammonia is colorless with a strong smell, and chlorine is a yellow-green poisonous gas. Proper safety equipment is necessary when handling chlorine.
Step-by-step explanation:
Yes, ammonia vapors and chlorine gas do react to form a white cloud, which can be used as an indicator to identify chlorine leaks. Ammonia (NH3) is a colorless gas with a noticeable pungent smell, and chlorine (Cl2) is a poisonous yellow-green gas. When they interact, they can produce a variety of nitrogen and chlorine-containing compounds, including ammonium chloride (NH4Cl). This reaction is visibly demonstrated when a white cloud of ammonium chloride forms upon the mixing of the two gases. Recognizing this white cloud can be a vital safety measure for operators in environments where chlorine gas is used or stored. Using protective equipment, such as a full body impermeable suit and a full face mask with filtration for chlorine compounds, is essential when handling chlorine to prevent exposure to this toxic and corrosive substance.
