Compare the reducibility of carbon with carbon monoxide

Activated carbon, also known as activated carbon. It is black powdery or lumpy, granular, honeycomb-shaped amorphous carbon, and there are also crystalline carbon with regular arrangement. In addition to carbon, activated carbon also contains two types of admixtures:

One is chemically bound elements, mainly oxygen and hydrogen, which remain in the carbon due to incomplete carbonization, or in the activation process, foreign non-carbon elements are chemically combined with the surface of activated carbon, such as when activated with water vapor, the surface of activated carbon is oxidized or oxidized by water vapor; Another type of admixture is ash, which is the inorganic part of activated carbon; Ash is easy to cause secondary pollution in activated carbon.

The valency of carbon in carbon monoxide is +2 valence, whereas the valency of carbon elemental is zero valence. In the chemical reaction, they can all undergo oxidation reaction, rising to the most ** state +4 valence, obviously, because the valence of carbon elements is lower, it is first oxidized to carbon monoxide and then oxidized to carbon dioxide, so carbon monoxide is more reducible, and carbon monoxide is solid, and the reflection effect is good.

Carbon monoxide bar (carbon monoxide is an unstable oxide of carbon, so it is easier to deoxygenate to produce its stable oxide, carbon dioxide).

C is stronger, C reduces the object to CO2 to be able to absorb two oxygen atoms.

The reducibility of carbon monoxide mainly refers to the reaction of carbon monoxide and metal oxides at high temperatures.

For example, carbon monoxide and iron oxide react to form iron and carbon dioxide under high temperature conditions, carbon monoxide and copper oxide react to form copper and carbon dioxide under high temperature conditions, and carbon monoxide and ferric tetroxide react to form iron and carbon dioxide under high temperature conditions, all of which reflect the reducing properties of carbon monoxide.

Properties of carbon monoxideCarbon monoxide is usually a colorless, odorless, and tasteless gas. 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.

The reasons why both carbon monoxide and carbon are reducible are: the valency of carbon element increases, in the reaction, carbon monoxide is converted to carbon dioxide, and the valency of carbon element increases; Carbon is converted to carbon dioxide, and the valency of carbon increases so that both carbon monoxide and carbon are reductive because the valency of carbon increases.

Reducibility refers to the ability of atoms, molecules, or ions to lose electrons in a chemical reaction. The stronger the electron-losing ability of the particles contained in the substance, the stronger the reducibility of the substance itself; Conversely, the weaker it is, the weaker its reducibility will be.

Carbon Monoxide Profile:

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), 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).

The reducibility of carbon refers to the ability of atoms, molecules or ions to lose electrons in chemical reactions, and carbon, as a reducing agent, has strong reducing properties and can reduce metal elements from metal oxides.

Second, the nature of carbonCarbon is a non-metallic element, the chemical symbol is C, it is stable at room temperature, not easy to react, low toxicity, widely exists in the atmosphere and crust and organisms in various forms, and can chemically self-combine to form a large number of chemical combinations.

1.Carbon reduction carbon dioxide reaction produces carbon monoxide: C + CO2 = high temperature = 2CO2Carbon reacts with oxygen (or metal oxides) to form carbon dioxide: C + O2 = ignition = CO2;

c + 2cuo = high temperature = 2cu + CO2 3C + 2Fe2O3= High temperature = 4Fe + 3CO2 [Don't understand and ask again.] 】

Carbon is both oxidizing and reducing. Examples of carbon having oxidizing properties:Carbon energy reacts with silicon to form silicon carbide with the reaction formula Si+C=SiC (condition:

high temperature);

Examples of carbon being reductive:Carbon energy can chemically react with oxygen to produce carbon dioxide with the reaction formula C+O2=CO2 (condition: ignition).

Carbon is both oxidizing and reducing. Oxidation refers to the property of a substance to obtain electrons. When a substance gains electrons, the valency decreases.

Reductive is only the property of a substance that loses its electrons. The valency is increased when a substance loses electrons. The valence of carbon elemental is zero, and the valence can be increased to positive two and four valents.

It can be lower to minus four. So it has both oxidizing and reducing properties.
