Video tapes generally use needle-shaped iron or iron oxide magnetic ultrafine particles, while nano-iron oxide is a new type of magnetic recording material. Soft ferrites are used in radio communications, radio and television, automatic control, aerospace, radar navigation, measuring instruments, computers, printing, household appliances, and biomedicine.

The chemical equation for the reaction of carbon monoxide with ferric oxide is: 3CO+Fe2O3=High temperature=2Fe+3CO2.

When ferric oxide reacts with carbon monoxide, ferric oxide is reduced to form iron powder, which is a black powder. Therefore, after the reaction, you will see the phenomenon that the powder changes from red to black.

The chemical equation for the reaction of carbon oxide and iron oxide is: 3CO+Fe2O3=High temperature=2Fe+3CO2. Iron is made by reducing iron oxide with carbon monoxide, mainly by using the reducibility of CO to react with iron oxide at high temperature to produce iron and carbon dioxide.

Carbon monoxide and iron oxide reactions

1. Under high temperature conditions, carbon monoxide reacts with iron oxide to form iron and carbon dioxide, and the reaction equation is: 3CO+Fe2O3=High temperature=2Fe+3CO2.

2. Under high temperature conditions, carbon monoxide reacts with iron oxide to form iron and carbon dioxide, and the color of Fe O powder changes from red to black.

3. The reduction of iron oxide by carbon monoxide 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, which shows that carbon monoxide is flammable and toxic.

Precautions for carbon monoxide reduction of iron oxide in the laboratory:

1. Reaction conditions: high temperature, if there is no powder blowtorch, a metal mesh cover can be added to the flame of the alcohol lamp.

2. CO is highly toxic, so when the experiment is carried out, it should be carried out in a fume hood, and the unreacted gas should be treated as an exhaust gas to avoid polluting the air.

3. Operation sequence: CO should "go out early and return late", and sprinkle fine blowtorch should "arrive late and leave early".

At the beginning of the experiment, CO is introduced to exhaust the air in the device to prevent CO from mixing with air and heating **; After the experiment, CO gas should be introduced until the glass tube is cooled to prevent the iron at high temperature from coming into contact with the air and being oxidized.

Carbon monoxideand iron oxide chemical equation is: 3CO+Fe2O3=High temperature=2Fe+3CO2.

Reaction principle: carbon monoxide is used as a reducing agent to seize the oxygen in the iron oxide, so that the iron oxide undergoes a reduction reaction to generate elemental iron; Whereas, carbon monoxide undergoes an oxidation reaction.

Carbon dioxide is generated.

Properties of carbon monoxide:

Carbon monoxide has the chemical formula CO and molecular weight, and is usually a colorless, odorless, and tasteless gas. Carbon monoxide is both reducing and oxidizing, and can undergo oxidation reactions (combustion reactions) and disproportionation reactions.

Wait. It is toxic, and at higher concentrations, it can cause people to have different degrees of poisoning symptoms, endangering the brain, heart, liver, kidneys, lungs and other tissues of the human body.

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

Since carbon monoxide reacts with iron oxide to form iron and carbon dioxide at high temperatures, iron oxide is red and the reduced iron 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 carbon monoxide shows that carbon monoxide is reduced by carbon monoxide, because the carbon monoxide in the exhaust gas cannot be discharged into the air, it will pollute the air and ignite, indicating that carbon monoxide is flammable and toxic.

The chemical equation for carbon monoxide and iron oxides: 3CO+Fe2O3=2FE+3CO2 (under the condition of heating).

Iron oxide red to reddish-brown powder, iron oxide is insoluble in water, organic acids and organic solvents, soluble in inorganic acids, and has two types: -type (positive magnetic) and -type (diamagnetic).

Iron oxide is stable to light, heat, and air. It is stable to acids and alkalis, has strong tinting strength, refractive index, melting point 1550, and decomposes at about 1565.

A certain amount of 5% ferrous sulfate solution is quickly reacted with excess sodium hydroxide solution (excess alkali is required, and air is introduced at room temperature to make it all turn into a reddish-brown iron hydroxide colloidal solution, which is used as the crystal nucleus for depositing iron oxide.

With the crystal nucleus as the carrier, with ferrous sulfate as the medium, the air is introduced, in the presence of metallic iron, the ferrous sulfate reacts with oxygen in the air to generate iron oxide (i.e. iron red) and is deposited on the crystal nucleus, and the sulfate in the solution reacts with the metal iron to regenerate ferrous sulfate, and the ferrous sulfate is oxidized into iron red by the air and continues to be deposited, so that the cycle ends to the end of the whole process to generate red iron oxide.
