Chemical properties of carbon monoxide, carbon monoxide carbon dioxide chemical properties

Carbon monoxide, a carbon oxide, with the chemical formula CO and molecular weight, is usually a colorless, odorless, and tasteless gas. In terms of physical properties, carbon monoxide has a melting point of -205 and a boiling point, which is insoluble in water (the solubility in water at 20 is g[1]), and it is not easy to liquefy and solidify. In terms of chemical properties, carbon monoxide is both reductive and oxidizing, and can undergo oxidation reactions (combustion reactions) and disproportionation reactions. At the same time, it is toxic, and at higher concentrations, it can cause people to have different degrees of poisoning symptoms, endanger the brain, heart, liver, kidney, lungs and other tissues of the human body, and even electrocution-like death, and the minimum lethal concentration of human inhalation is 5000 ppm (5 minutes).

Industrially, carbon monoxide is the basis of one-carbon chemistry, which can be prepared by methods such as coke oxygen method, and is mainly used for the production of methanol and phosgene and organic synthesis.

The chemical properties of carbon monoxide are:

1) Carbon monoxide is obtained from the incomplete combustion of carbon or carbon-containing organic matter, which can be burned in air or oxygen to become carbon dioxide, emitting a large amount of heat, and the flame is blue, which can be used as fuel.

2) Carbon monoxide has strong reducibility and is commonly used in industry to smelt metals and reduce metals from their oxides. For example, co+cuo=δ=cu+CO2

3) Carbon monoxide is easy to combine with human hemoglobin, so that hemoglobin loses its oxygen-carrying capacity, and the body is poisoned due to lack of oxygen, so carbon monoxide is toxic.

Carbon monoxide is chemically flammable and highly reducible.

The chemical properties of carbon monoxide mainly include: flammable, reducible, and also a toxic gas. Carbon dioxide is chemically inactive and relatively stable.

4. Viscosity. , 0, numeric value.

5. The lowest ignition point in the air.

6. Character. No bridge traces, no odor, no taste.

Carbon Monoxide Main Uses:

1. Carbon monoxide can be used to make sodium formate.

2. It is used as a reducing agent in the metallurgical industry, such as industrial reduction of iron oxide (preparation of iron).

3. It is used to make gaseous fuels, such as water gas (a mixture of carbon monoxide and hydrogen and other gases).

4. As a reducing agent, carbon oxide can reduce many metal oxides into metal elements at high temperature or heating, so it is often used in metal smelting. Carbon monoxide can be combined with hydrogen to form simple organic matter, which is oxidizing. <>

1. Carbon monoxide can be burned to produce carbon dioxide, which is flammable.

2. Carbon monoxide can react with iron oxides to form iron and carbon dioxide, which is reducible.

3. One acre of positive carbon oxide has a high toxicity. CO is an electron pair donor, which can combine with the ferrous of hemoglobin to form a coordination to affect the transport of oxygen in hemoglobin, and CO has strong reducibility and can react with active metal oxides to prepare metals.

Chemical properties of carbon monoxide:

It is flammable and can be burned to produce carbon dioxide; It is reducible and can react with iron oxides to produce iron and carbon dioxide, which are used to make metals; Highly toxic, CO is an electron-pair donor that can bind to the ferrous hemoglobin to form a coordination that affects the transport of oxygen by hemoglobin.

Carbon Monoxide Profile:

1. Physical properties of carbon monoxide.

Under normal conditions, carbon monoxide is a colorless, odorless, tasteless, insoluble gas in water, melting point, boiling point. Under standard conditions, the density of the gas is neutral.

2. The electronic formula and structure of carbon monoxide.

The outermost shell of carbon has four electrons, and the outermost shell of oxygen has 6 electrons, so that the two single electrons of carbon enter the p orbital of oxygen and the two single electrons of oxygen pair together to form a bond, so that two bonds are formed, and then the lone electron pair of oxygen enters the empty p orbital of carbon to form a matching bond, so that three bonds are formed between oxygen and carbon.

3. Molecular structure of carbon monoxide.

The carbon monoxide molecule is polar but the polarity of the molecule is weak due to the presence of feedback t-bonds. The shape of the molecule is linear.

4. Precautions for carbon monoxide.

Carbon monoxide poisoning is commonly caused by poor ventilation in homes, leaks in gas or liquefied gas pipes from coal stoves, or inhalation of industrial gas and carbon monoxide in mines.

Chemical properties of carbon monoxide: At room temperature, carbon monoxide does not react with acids and alkalis, but can be mixed with air to form a first-class mixture, which can cause combustion when exposed to open flames and high temperatures, which is a flammable and explosive gas. Because the valency of carbon in the carbon monoxide molecule is +2, it can be oxidized to +4 valence, which is reducible; And it can be reduced to a low-valence state, which has oxidizing properties.

Chemical properties of carbon monoxide:1. Flammability: 2CO+O22CO2

2. Reductibility:

Carbon monoxide reduced copper oxide: CO+cuoCu+CO2 carbon monoxide reduced iron oxide: 3CO+Fe2O32Fe+3CO2 carbon monoxide reduced ferric oxide:

4CO+FE3O43FE+4CO23, toxicity: CO is very easy to combine with hemoglobin in the blood, so that hemoglobin can not be well combined with oxygen, resulting in hypoxia in the organism, which is life-threatening in severe cases. CO is highly toxic, and people who stay in the air for 2-3 hours when the volume fraction of CO reaches the symptoms of poisoning appear, so we should install chimneys when using coal and gas water heaters and pay attention to indoor ventilation.

Carbon monoxide. It is a carbon oxide with the chemical formula CO. The properties of carbon monoxide are mainly divided into physical properties and chemical properties.

The first is the physical properties, under normal conditions, carbon monoxide is a colorless, odorless, tasteless, insoluble in water neutral gas, melting point, boiling point. The density of the gas under the standard condition is , and the density of the air.

The difference is very small under standard conditions. The second is chemical properties, which are flammable, reducible, toxic, and extremely weak oxidation. Among them, carbon monoxide is used as a reducing agent, which can reduce many metal oxides into metal elements at high temperature or heating, so it is often used in metal smelting.

Carbon monoxide is extremely high in the blood.

Prone to hemoglobin.

Combine to form carboxyhemoglobin, so that hemoglobin loses its oxygen-carrying ability and effect, causing tissue suffocation, and death in severe cases, so be sure to avoid inhaling carbon monoxide.
