Carbon monoxide (carbon monoxide) is the gas which is found in places where conditions for incomplete combustion of carbon are created. It is called carbon monoxide. It is very poisonous and even at rather small concentration can be deadly to the person.
Physical and chemical properties of carbon monoxide
Carbon monoxide, or carbon monoxide (CO) - gas without color, a smell and taste. Burns with a blue flame as hydrogen. Because of it in 1776 the chemists mixed it with hydrogen when they for the first time received carbon monoxide by zinc oxide heating with carbon. The molecule of this gas has strong threefold connection, like a nitrogen molecule. That is why some similarity between them is found: temperatures of melting and boiling are almost identical. The molecule of carbon monoxide has high value of potential of ionization.
Being oxidized, carbon monoxide forms carbon dioxide. At this reaction a large amount of thermal energy is emitted. That is why carbon monoxide is applied in heating systems.
Carbon monoxide at low temperatures almost does not react with other substances, in case of high temperatures the situation is different. Very quickly there take place reactions of accession of various organic matter. The mix CO and oxygen in certain ratios is very dangerous because of a possibility of its explosion.
Receiving carbon monoxide
In vitro carbon monoxide is received by decomposition of formic acid. It happens under the influence of the hot concentrated sulfuric acid, or at its transmission through phosphorus oxide. One more way is that mix of ant and oxalic acids is heated to a certain temperature. The allocated CO can be removed from this mix, having passed it through barytic water (saturated solution of hydroxide of barium).
Danger of carbon monoxide
Carbon monoxide is extremely dangerous to the person. It causes severe poisoning, quite often can become a cause of death. The thing is that carbon monoxide has ability to react with the blood hemoglobin which is carrying out oxygen transfer to all cells of a body. As a result of such reaction it is formed karbogemoglobin. Because of a lack of oxygen of a cage experience starvation. It is possible to allocate the following symptoms of poisoning: nausea, vomiting, headache, loss of color sensation, disorder of breath and others. The person who got poisoned with carbon monoxide needs to give first aid as soon as possible. At first it needs to be pulled out on fresh air and to put the cotton wool moistened in liquid ammonia to a nose. Further to pound a breast of the victim and to put hot-water bottles to his legs. Plentiful warm drink is recommended. It is necessary to call at once after detection of symptoms the doctor.
