Iron oxide is introduced into carbon monoxide.
A redox reaction occurs.
3CO+FE O = 2FE+3CO (Condition: High Temperature).
Phenomenon: The red substance gradually turns black (the color of Fe powder), and the lime water is clarified.
Becomes cloudy. In the experimental process of carbon monoxide reduction of iron oxide, carbon monoxide should be introduced first, and then heated, the purpose is to use carbon monoxide to clean the air in the device and prevent the occurrence of heating experiments.
After the reaction between carbon monoxide and iron oxide, the heating should be stopped, and the carbon monoxide should be continued until it is cooled, and then the carbon monoxide should be stopped, so as to prevent air from entering and re-oxidize the iron generated.
Iron oxide is the main component of rust. The main cause of rust is that iron metal will rust in the presence of impurity carbon, which reacts with moisture and oxygen in the environment.

Carbon monoxide reacts with iron oxide, and those who want to know what reaction is going to take a look.

No response
Iron hydroxide does not react with carbon monoxide. Iron oxide and carbon monoxide react.
E(OH)3 forms Fe2O3 at high temperatures, and CO can react with Fe2O3 at high temperatures, and iron oxide and carbon monoxide will undergo redox reactions. 3CO+FE O = 2FE+3CO (Condition: High Temperature).
Phenomenon: The red substance gradually turns black (the color of Fe powder), and the clarified lime water becomes turbid.
The reduction of iron oxide by carbon monoxide shows that carbon monoxide is reducible, because the carbon monoxide in the exhaust gas cannot be discharged into the air, it will pollute the air, and it is ignited, indicating that carbon monoxide is flammable.
Iron hydroxide, also known as high iron hydroxide, chemical formula Fe(OH)3, molecular spine loss. Brown cubic crystals or brown flocculation precipitate. Heat to more than 500 and dehydrate to iron oxide.
Insoluble in water, ethanol and ether, the newly prepared is soluble in inorganic acids and organic acids, and it is difficult to dissolve when placed for aging. Sodium ferrite can be obtained by eutectic with sodium carbonate. It is prepared by the reaction of ferric nitrate or ferric chloride with ammonia water to form precipitate.
It is used as a purifying agent, an absorbent, and is used to make pigments, medicines, and arsenic poisons. Mixed with calcium oxide, cyanide and hydrogen sulfide in coal gas can be removed.
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).
Industrially, carbon monoxide is the basis of carbon permeation chemistry, which can be prepared by coke oxygen method and other methods, and is mainly used for the production of methanol and phosgene and organic synthesis.

The equation for the reaction of iron oxide and carbon monoxide is: 3CO+FE2O3=High temperature=2FE+3CO2.
At high temperatures, carbon monoxide reacts with iron oxide to form iron and carbon dioxide, and the color of FeO powder changes from red to black. Iron oxide and carbon monoxide will undergo a redox reaction, the red substance will gradually turn black, and the clarified lime water will be turbid.
Principle. Because under high temperature conditions, carbon monoxide reacts with iron oxide to form iron and carbon dioxide, iron oxide is round bucket swimming red, and the reduced iron orange powder is black. Therefore, from the beginning of heating to the end of the experiment, the color of Fe2O3 powder changed from red to black.
The reduction of iron oxide by a pin of auspicious carbon oxide shows that carbon monoxide is reduced by carbon monoxide, because the carbon monoxide in the tail gas cannot be discharged into the air, it will pollute the air, and it is ignited, indicating that carbon monoxide is flammable and toxic.

Heating iron oxide can make it oxidize deeper, and adding carbon oxide can change the properties of metal welding materials, which will react to form a welding material - carbon dioxide welding rods. When iron oxide and carbon monoxide react together, carbon dioxide electrodes (CO2) are formed. When it reacts, it releases a lot of heat and spectrum, which can be used to make stainless steel parts in processes such as welding, machining, etc.

Heating iron oxide produces hydrogen and carbon dioxide, while nitric oxide can be produced by carbon monoxide such as sedan carbon, which can contribute to air pollution. Secondly, heating iron oxide and carbon monoxide produces toxic chlorine gases, so ventilation should be taken care of when performing this reaction and ensuring that there is enough fresh air in the laboratory. In addition, protective clothing should be worn to prevent exposure to toxic gases.

Heating iron oxide and then introducing carbon monoxide will cause the iron ions contained in the iron oxide to be oxidized to iron oxide, thus losing its original properties.
-
If carbon monoxide is introduced after heating iron oxide, then iron oxide will be sold to form iron carbonate, which is a very precipitate that will be deposited on the surface of iron oxide, affecting the heat conduction cavity of iron oxide and reducing the availability of iron oxide.

**。Because at very high temperatures, CO and O2 react rapidly to form CO2, which expands violently.
Iron oxide will still be reduced after the hall is finished, because the iron is heated at a high temperature, which is equivalent to heating when it is introduced.
