Does sulphur dioxide react with copper? What would you do if so? If not, then why?

Based on the similarity between sulfur dioxide and carbon dioxide in non-redox reactions, I think Cu can be generated with SO2 in a humid environment Basic copper sulfite : 2Cu + O2 + SO2 + H2O == Cu2(OH)2SO3 I remember that at high temperatures, by oxidizing sulfide ores, to convert into oxides, and then for reduction, is a common way to refine some metals in the form of sulfides, such as oxidizing Cu2S or Cus with O2, so that they can produce Cuo and SO2. This phenomenon shows that the sulfides of copper are not as stable as oxides, and the elemental substances are not as stable as oxides, so it is unlikely that Cu and SO2 react at high temperatures to form Cuo and S.

Sulfur dioxide. It can react with copper, the condition is heating, and there are two cases of reaction: 1

SO2 + 2Cu = Heating = S + 2Cuo (S + Cu = Heating = Cus) 2Excess sulfur dioxide SO2 + 2Cu = heating = S + 2Cuo After cooling, SO2 + Cuo = CuSO3

It reacts, SO2 has strong oxidizing and reducing properties, and copper has reducing properties. Therefore, it will react, Cu+SO2=CuS+O2, which is purely my opinion.

Probably not, the reduction of sulfur is greater than that of copper, and if it reacts, sulfur and copper oxide will be generated, but sulfur is more reducible than copper, and copper and sulfur dioxide will be generated, so it will not react. Hope.

Urium dioxide is generally reduced in chemical reactions (such as making acidic potassium permanganate and halogen elements, iron ions fade, etc.), with weak oxidation, only strong oxidation can oxidize copper into copper ions, so it should not be.

Sulfur dioxide is reducing, but it also has a certain oxidizing property It reacts with copper oxide heating to form copper sulfite, and the copper sulfite is oxidized to copper sulfate cuo+so2=cuso3,2cuso3+o2=2cuso4

The reaction equation of copper oxide and dilute sulfuric acid is: Cuo H2SO4 CuSO4 H2O.

Reaction phenomenon: The black copper oxide solid dissolves, and the resulting solution appears blue.

The reaction of copper oxide and dilute sulfuric acid belongs to the reaction of acid and metal oxide, which belongs to the metathesis reaction in the basic reaction. The metathesis reaction is a reaction in which two compounds exchange components with each other to produce two other compounds. It can be abbreviated as ab+cd=ad+cb.

Copper oxide is mainly used.

1. It can be used as a catalyst for organic synthesis, as an analytical reagent (for nitrogen determination), an oxidant, a catalyst and a petroleum desulfurizer, and can also be used for the determination of carbon in organic compounds.

2. It is used as a colorant in glass, enamel and ceramic industries, an anti-zoning agent for paint, and a polishing agent for optical glass. It is used in the manufacture of dyes, organocatalyst supports, and copper compounds. It is also used in the rayon manufacturing industry and as a desulfurizer for grease.

It is used as a raw material for the manufacture of other copper salts, and is also a raw material for making artificial gemstones.

Summary. The reaction between copper sulfate solution and hydrogen sulfide is because the copper ions provided by copper sulfate and the sulfur ions provided by hydrogen sulfide aqueous solution combine to form copper sulfide, which is an insoluble substance, copper sulfide, and the reaction meets the conditions of metathesis reaction, so it is a metathesis reaction type.

Why copper sulphate can react with hydrogen sulfide.

Hello oh dear. Please wait.

The reaction between copper sulfate solution and hydrogen sulfide is because the copper ions provided by copper sulfate and the sulfur ions provided by hydrogen sulfide aqueous solution combine to form copper sulfide, which is an insoluble substance, copper sulfide, and the reaction meets the conditions of metathesis reaction, so it is a metathesis reaction type.

Is it there? I'm glad to answer this chemistry question for you, and I hope it can help you <>

What's the matter with weak acids making strong acids.

This does not need to consider the weak acid to make strong acid, but to respect the experimental facts, this experiment is easy to see the formation of copper sulfide precipitation, meet the metathesis reaction conditions, but also respect the objective facts of the chemical reaction.

It is an objective fact that the generated copper sulfide is too insoluble and insoluble in the sulfuric acid generated, and such an equation can also be regarded as a special case that does not conform to the strong acid to the weak acid. Chemical reactions should be based on objective facts.

Sulfur and concentrated sulfuric acid react why sulfur dioxide is not marked with gas symbols.

S+2H2SO4 (concentrated) 3SO2 +2H2O

I don't know if you see the gas symbol in **.

1. Reaction of copper oxide and dilute sulfuric acid.

The chemical equation for the reaction of copper oxide and dilute sulfuric acid is:

cuo+h2so4= cuso4+hso

The phenomenon is that the amount of black solid decreases, and the solution changes from colorless to blue.

Copper oxide can react with dilute sulfuric acid, CuO+H2SO4= CuSO4+H2O, which belongs to the metathesis reaction in the basic reaction.

【Operation】1 Put a small amount of black copper oxide powder in a test tube, then add an appropriate amount of dilute sulfuric acid, and heat it slightly on an alcohol lamp.

2 The black copper oxide gradually dissolves, and the solution turns from colorless to blue.

2. The ionic equation for the reaction of copper oxide with dilute sulfuric acid.

cuo+2h+= cu2+ +2h2o。

Copper sulfide reacts with sulfuric acid, but because the solubility product of copper sulfide is too small, it is difficult to dissolve in dilute sulfuric acid, so copper sulfide does not react with dilute sulfuric acid. Copper sulfide reacts with dilute nitric acid or concentrated sulfuric acid.

Copper sulfide is an inorganic compound, the chemical formula is Cus or CuI2Cuii(S2)S, so in fact, two-thirds of the sulfur is persulfide ions, two-thirds of the copper is cuprous ions, black-brown, extremely insoluble, one of the most insoluble substances, second only to silver sulfide, mercury sulfide, palladium sulfide and aplatin sulfide, etc., because its insolubility makes some seemingly impossible reactions can occur.

2cu+s=cu2s

conditions, heated, are produced is cuprous sulfide.

Because of the oxidizing nature of S.

It's not very strong, this is a high school knowledge point, a college entrance examination point.

In this experiment, the sulfur powder is placed in a test tube, the mouth of the test tube is destroyed to the bucket, and the sulfur will gradually melt and produce a vertical pin to search for sulfur vapor.

Then extend a thin bundle of copper wire into the test tube and extinguish the alcohol lamp.

It can be observed that copper wires can react rapidly with sulfur vapor to remain red hot, forming a black substance. It means that the reaction can be exothermic, so the heat released by the reaction can keep the reaction going on without continuous heating.

Summary. Hydrogen peroxide and dilute sulfuric acid react to produce water and oxygen.

Dear, I saw your question and am sorting out the answer, and I will reply within five minutes.

Hello, are you hail book said that hydrogen oxide and sulfuric acid reaction? There is no such thing as hydrogen peroxide and sulfur smiling copper. Please describe the problem clearly. Moreover, the reaction between hydrogen peroxide and sulfuric acid does not produce sulfur, but the combination of sulfuric acid and hydrogen peroxide produces peroxide monosulfuric acid.

The fifth question is written in the information-based ion equation, why is it sulfur element, not sulfur dioxide?

Hello, you sent it**, my side is in a fuzzy state, the platform has regulations, and the ** sent by users is in a fuzzy state because it involves privacy.

You can send the original question over, not in the form of **, and I will answer it again.

The answer is yes.

It is not sulfur dioxide, which requires concentrated sulfuric acid.

Then why can't it be that the sulfur of copper sulfide has changed from minus two to plus six to the sulfur of copper sulfate.

Copper sulfide is insoluble in dilute sulfuric acid.

Copper sulfide is dissolved in concentrated sulfuric acid.

Copper sulfide plus concentrated sulphuric acid produces sulphur dioxide and sulphur.

Got it, no. Ah this, I don't understand why, isn't it dilute sulfuric acid here, I mean that the process of copper disulfide to sulfuric acid is not written in the process of messing around, why can't it be minus two to positive six calendar hands, but the positive hexavalent sulfur of sulfuric acid to the positive hexavalent sulfate of copper sulfate.

Because copper sulfide is insoluble in dilute sulfuric acid.

I don't react at all.

Yes, but conditionally, directly pass sulfur dioxide into the copper sulfate solution, they will not react, only SO2 + H2O H2SO3 will occur, unless it is passed into the saturated mixed solution of copper sulfate and sodium chloride to generate cuprous chloride precipitate, the chemical formula CuCl, so that the reaction can move forward, 2Cu2+ +2Cl- +SO2 +2H2O 2CuCl (precipitation) +SO42- 4H+, in this reaction, copper ions are used as oxidants, Sulfur dioxide is used as a reducing agent.
