Key Concepts
These are the key concepts you need to understand to accurately answer the question.
neutral gas
Carbon monoxide (CO) is classified as a neutral gas. This means it does not exhibit acidic or basic properties.
Neutral gases do not affect the pH levels of their surroundings.
They are non-polar molecules and do not react with water to form ions.
For instance, carbon monoxide does not turn litmus paper red or blue because it is neither acidic nor basic in nature.

ammonical cuprous chloride absorption
Carbon monoxide can be absorbed by a solution of ammonical cuprous chloride.
This solution contains ammonia and cuprous chloride (CuCl).
When CO is introduced to this solution, it forms a stable complex, [Cu(CO)]_n, thereby removing CO from the gas mixture.
This property is often utilized in gas analysis to determine the presence and concentration of CO.

carboxyhemoglobin formation
Carbon monoxide can bind with hemoglobin in blood to form carboxyhemoglobin (HbCO).
Hemoglobin typically binds with oxygen to transport it throughout the body.
However, CO has a much higher affinity for hemoglobin than oxygen, binding about 200 times more tightly.
This means that when CO is present, it can significantly reduce the blood's ability to carry oxygen, which can lead to serious health issues like carbon monoxide poisoning.

flammability
Carbon monoxide is a highly flammable gas.
It can easily catch fire and support combustion, making it a hazardous substance in environments where there may be open flames or sparks.
Due to these properties, CO cannot be used as a fire extinguisher. In fact, using CO for this purpose would be extremely dangerous and counterproductive.
