What kind of gas is the charcoal reduction copper oxide ignition process?

The first is CO2 and Cu generated by carbon and copper oxide.

CO2 + Ca(OH)2 to generate CaCO3 + H2O(=, no gas is easy to collect. But if it's two chain reactions (cuo and co heating reactions, a small amount of carbon dioxide and clarified lime water). Look at that diagram.

Because when CO is introduced, it is impossible for CUO and CO to complete all the reactions, and carbon monoxide gas will definitely rush out of the duct to the clarified lime water, and carbon monoxide and clarified lime water cannot react, so carbon monoxide will be collected.

Carbon reacts with copper oxide to produce carbon dioxide.

Carbon monoxide is produced by carbon and carbon dioxide at high temperatures.

What is collected is the remaining carbon monoxide, and there is no end to the reaction. The carbon dioxide reacts with the clarified lime water.

Not necessarily, carbon monoxide may be, because carbon and copper oxide can form a mixture of carbon dioxide and carbon monoxide, depending on the relationship between the quantity. Also, lime water can't absorb all the carbon dioxide because calcium hydroxide is too soluble, so you see

First of all, it is certain that carbon and copper oxide do not react, it is carbon and oxygen that react to produce carbon monoxide, and carbon monoxide reacts with copper oxide to produce carbon dioxide and copper, and of course carbon monoxide is collected, otherwise you will faint after sitting for a while. Carbon monoxide is made up of carbon and carbon dioxide. It's impossible to do all the carbon monoxide reactions.

Both of these reactions will have carbon monoxide. The first one is produced because of insufficient oxygen. The second is because there is no response.

Therefore, it must be collected and processed centrally. Avoid polluting the air.

Chemical equation for reduction of copper oxide by charcoal:

c＋2cuo＝＝＝2cu＋co₂↑

Hydrogen or carbon monoxide can be reduced to metallic copper by introduction of hydrogen or carbon monoxide at high temperatures. Copper oxide is heated in air and reduced to cuprous oxide by releasing oxygen at about 1050.

In hydrogen or carbon monoxide gas streams, it can be easily reduced to copper metal, even below 250. Although copper oxide is insoluble in water, it can be dissolved in aqueous solution of alkali metal hydroxide.

Charcoal reduces copper oxide.

The phenomenon is: "The black powder gradually turns into a bright purple-red color, and the gas is passed into the clarified lime water, so that the clarified lime water is made."

cloudy, sometimes accompanied by the formation of dark red solids with poor holes".

The chemical equation of the reaction.

C+2Cuo = 2Cu+CO2 (displacement reaction.

The condition of the reaction is high temperature).

Charcoal reduces copper oxide.

Experimental phenomenon: copper oxide is black powder, and copper is red powder. Therefore, the most obvious phenomenon in the experiment is that the black powder turns red, and if there is an exhaust gas treatment device, the exhaust gas passes through the clarified lime water.

It can make lime water turbid.

After heating the mixed powder of charcoal and copper oxide for a certain period of time, part of the reaction mixture began to burn. Remove the alcohol lamp at this point.

The combustion continues, and after a few seconds the combustion is complete and the reaction stops. Combustion itself glows and heats up.

When combustion begins, the heating is stopped and the combustion continues, confirming that the heat released by the reaction is sufficient to raise the temperature of the unreacted mixture to the temperature required for combustion.

Charcoal reduces copper oxide, and the chaos brother frequently originates from Youyi 100, and the class Zheng spare parts are well-made and shouted to accompany the destruction.

The chemical equation for the reduction of copper oxide by charcoal: C 2Cuo 2Cu CO2

Charcoal is a dark brown or black porous solid fuel left over from incomplete combustion of wood or wood-based raw materials or pyrolysis in the absence of air. Charcoal is an impure amorphous carbon that retains the original structure of the wood and the residual tar in the pores. Charcoal was used for the smelting of bronzes of the Shang Dynasty and iron tools of the Spring and Autumn Period and the Warring States Period in China, and its hygroscopicity was used to observe climate change.

High temperature reduction c+2cuo=2cu+CO2 (conditional high temperature).

The main reaction between charcoal and copper is charcoal and copper oxide.

Copper and carbon dioxide are generated.

When there is an excess of carbon in the reaction, charcoal and copper oxide can produce copper and carbon monoxide.

When there is an excess of copper oxide in the reaction, charcoal and copper oxide can produce copper oxide and carbon dioxide.

In this reaction, copper oxide loses oxygen and becomes elemental copper. The reaction in which the oxygen in this oxygenated compound is taken away is called a reduction reaction. where carbon is the reducing agent.

Charcoal is a substance that reduces copper oxide to copper, and it is reducible.

The reducibility of elemental carbon can be used in the metallurgical industry.

Experimental phenomenon: the black powder gradually turns into a bright purplish-red, and the gas is passed into the clarified lime water, which makes the clarified lime water.

Becomes cloudy. Sometimes it is accompanied by the formation of a dark red solid (cuprous oxide.

The precautions for the charcoal reduction copper oxide experiment are to withdraw the catheter after the experiment, if the alcohol lamp is evacuated first, it will cause backgasping due to air pressure, and it is best to keep hydrogen gas in the catheter to prevent the copper from being oxidized again. The experimental phenomenon of charcoal reduction of copper oxide is that the black solid turns purple-red, and the clarified lime water becomes turbid.

Charcoal Reduction Copper Oxide protocol.

1. Install the instrument from bottom to top, and tilt the test tube slightly downward.

2. After the charcoal powder and black copper oxide are fully dried, weigh the two black powders according to a certain quality ratio, put them into a mortar and grind them repeatedly and mix well.

3. Put the black mixture into the bottom of the test tube with a medicine spoon or small paper tray, plug the right-angled glass catheter with a rubber stopper, and insert the other end of the glass catheter into another test tube containing clarified lime water.

4. Light the alcohol lamp, preheat the test tube first, and then concentrate on the mixed powder to strengthen the heat.

5. Withdraw the glass conduit that extends into the test tube containing the clarified lime water, and then withdraw the alcohol lamp. After the test tube is cooled (to prevent air from entering the test tube when cooling), the test tube is removed from the iron table, and the powder in the test tube is poured on a clean white paper, and the powder is spread out and observed.

1..Mix well 2Strengthens heat 3Pay attention to putting cotton at the air inlet and outlet to prevent the powder from clogging the catheter4It is completely cooled and then opened to prevent the reduced copper from being oxidized by the air.

1.The mouth of the test tube should be slightly lower than the bottom of the test tube.

2.The test tube clamp should be clamped at 1 3 places away from the test tube mouth.

3.At the end of the experiment, the catheter was removed from the lime water and the alcohol lamp was removed4Add a mesh cover to the flame of the alcohol lamp to concentrate the flame and raise the temperature 5Preheat before heating and then heat.

6.After cooling, it is opened again to prevent the reduced copper from being oxidized by the air.

The black powder gradually turns into a bright purple-red, and the generated gas carries the source into the clarified lime water, making the clarified stone and blue gray water turbid. Sometimes it is accompanied by the formation of a dark red solid (cuprous oxide.

Experimental principle. The main component of charcoal is carbon, and carbon and copper oxide are reduced at high temperatures to form carbon monoxide and copper, and this phenomenon takes a certain amount of time.

In the early stage of the anti-Hui response, the first thing to do is to warm up, and the phenomenon you see will be that bubbles will be generated, and the speed is faster, and the bubbles here are to remove the air in the test tube.

After a while, it can be observed that the clarified limestone slowly becomes cloudy, but the copper oxide on the surface does not change.

In the middle of the experiment, it can be found that the copper sheet slowly turns from black to red, which is the effect of the reduction of copper oxide.

Later in the experiment, you will notice that the turbid lime water becomes clearer, indicating that the carbon monoxide produced is absorbed.

Finally, the whole copper sheet is bright red, and the alcohol lamp of the exhaust gas treatment also absorbs the gas, and the whole experimental phenomenon is like this, I hope it can be understood.
