What are copper sulphate and silver nitrate?

Classmate, it seems that you still don't know what metal salt is all about......Let me take copper sulfate as an example, the molecular formula of the so-called copper sulfate CuSO4, where Cu refers to the cation in this metal salt is copper ion, and SO4 is anion, that is, sulfate ion. If this substance is in water, then this metal salt will decompose into these two ions in the water, stay in the water, and if you evaporate the water, then these two ions will not be able to continue to be in an ionic state, then they will combine to become this salt.

Having said all this nonsense, it is actually saying that copper sulphate is a metal salt, and its name has little to do with how it is generated. For example, if you put copper sulfate and silver nitrate into water at the same time, then there will be four ions in the water, and if the water is evaporated at this time, then the last remaining solid is copper sulfate, silver sulfate, copper nitrate, silver nitrate, which is a mixture.

As for the equation that generated them, it can be said that generally we do not use these two things to react directly to prepare copper sulfate. In fact, they do react, but there are heating conditions, but there are other more complex products. That's not the case now, in short, metal salts are like that.

I don't know if you understand, I recommend reading more chemistry textbooks in the third year of junior high school.

Copper hydroxide can be obtained by reacting with sulfuric acid.

Silver and nitric acid can react to form silver nitrate, and of course, nitric acid has a high concentration.

Copper sulphate is obtained by the heating reaction of copper with concentrated sulphuric acid, and dilute sulphuric acid does not react with copper.

Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O Silver nitrate is the concentrated and dilute reaction obtained by the reaction of silver and nitric acid.

3AG + 4HNO3 = 3AGnO3 + No + 2H2O rare.

AG + 2HNO3 = AGnO3 + NO2 + H2O concentrated.

This is the subject of a chemical reaction, sulfuric acid does not react with copper in a large area. Nitric acid does not accumulate and react with silver. So this should be the reaction of other materials to get this material.

This is because the order of metal activity of copper and silver is after hydrogen, and it cannot be replaced with hydrogen ions. Only in strongly oxidizing acids, redox reactions occur. Nitric acid and concentrated sulfuric acid are strongly oxidizing and acidic, and can oxidize copper and silver, while dilute sulfuric acid and hydrochloric acid are only acidic and cannot react with copper and silver.

Because the oxidation of nitric acid and concentrated sulfuric acid is N5+ and S6+ respectively, nitric acid is reduced to No or No2, SO2, copper and silver are oxidized to form Cu2+Ag+, while dilute sulfuric acid and hydrochloric acid show the oxidation of hydrogen ions, and copper and silver are ranked after hydrogen in the metal activity order table, so they do not react.

The reaction of copper and silver nitrate is Cu+2AgNO3 Cu(NO3)2+2Ag. The phenomenon is that a silvery-white solid adheres to the surface of the copper, and the solution changes from colorless to blue.

Because copper is more active than silver, copper reacts with silver nitrate to form silver and copper nitrate, silver is silvery-white, and the copper ion solution is blue, so the reaction phenomenon is that the surface of copper is attached to a silver-white solid, and the solution changes from colorless to blue; The reactants of the reaction of copper with silver nitrate are copper and silver nitrate, and the products are silver and copper nitrate.

Introduction to Silver Nitrate:

Silver nitrate turns gray-black when exposed to organic matter, decomposing into silver. Pure silver nitrate is light stable, but due to the lack of purity of the general product, its aqueous solution and solids are often stored in brown reagent bottles.

When silver nitrate is heated to 440, it decomposes into silver, nitrogen, oxygen and nitrogen dioxide. The aqueous solution and the ethanol solution react neutrally to litmus with a pH of about 6. Boiling point 444 (decomposition).

Oxidizing. In the presence of organic matter, the light becomes gray or grayish-black. Silver nitrate can precipitate or coordinate with a range of reagents (see Coordination Compounds).

Reaction phenomenon of copper and silver nitrate: because copper is more active than silver, copper reacts with silver nitrate to form silver and copper nitrate, silver is silvery-white, and copper ion solution is blue, so the reaction phenomenon is that the surface of copper is attached to silver-white solid, and the solution changes from colorless to blue; Copper reacts with silver nitrate, and the products are silver and copper nitrate, which can be leveled by observation.

Copper and silver nitrate solution react to the surface of copper will adhere to a layer of silvery-white solid, and the color of the solution will change from colorless to blue. This is because copper is more active than silver, so copper and silver nitrate will produce silver and copper nitrate in the process of reaction, silver is silvery-white, and copper nitrate is blue, so that the color of the solution will change from colorless to blue, this reaction is a kind of displacement reaction.

Displacement reaction. Displacement reaction is one of the basic types of inorganic chemical reactions, which refers to the reaction of one element and one compound to produce another element and another compound. In the displacement reaction, only one of the positive or negative ions will be replaced, and the ions that are not reacted are bystanders.

Displacement reactions are generally considered redox reactions, but some special reactions, such as displacement between metal carbonyl compounds, are not redox reactions. In addition, it can also refer to the displacement reaction between Lewis acids, where no elemental substances are required to participate in the reaction.

Put a piece of clean copper wire in the test tube containing the silver nitrate solution, and after a while, we can see that the surface of the copper wire is covered with a layer of white silver.

This reaction is a displacement reaction because they are one elemental substance and one compound reacts to produce another compound and element. In general, only the first metals (starting with magnesium in the table of metal activity) can displace the latter metals from their salt solution.

The chemical formula of the reaction between copper and silver nitrate is: Cu+2AGnO3=Cu(NO3)2+2AG.

Analysis: Since copper is more active than silver, copper reacts with silver nitrate to form silver and copper nitrate, silver is silvery-white, and the copper ion solution is blue.

Reaction phenomenon: The surface of copper adheres to a silvery-white solid, and the solution changes from colorless to blue.

Dangers of silver nitrate:

**Contact: Remove contaminated clothing and rinse thoroughly with soapy and clean water**.

Eye contact: Lift the eyelids, rinse with running water or saline, and seek medical attention.

Inhalation: Quickly remove from the scene to fresh air. Keep your airways open. If you have difficulty breathing, give oxygen. If breathing stops, artificial respiration is performed immediately. Medical treatment.

Ingestion: Rinse your mouth with water, give milk or egg whites, and seek medical attention promptly.

Hazard characteristics: inorganic oxidants. When combustibles catch fire, it can fuel the fire. It is decomposed by high heat to produce toxic nitrogen oxides.

Fire extinguishing method: use water, mist water, sand, carbon dioxide to extinguish the fire.

Copper can react with silver nitrate. When the two react, the copper gradually disappears and a silvery-white substance is produced that adheres to the surface of the copper. It is expressed by the equation as: Cu+2AGnO3=Cu(NO3)2+2AG.

On the surface of the purple-red solid (copper) there is a solid precipitation, the solid from black, gray, gradually to white, silvery-white, and finally the solution from colorless to blue. Copper is dissolved, the volume is reduced, the solution changes from colorless to blue, the copper surface is black, the solid is produced, the copper surface is silver (black) (invisible), the substance is precipitated, the solution gradually becomes lighter, the blue copper reacts with silver nitrate, and a solid (silver) appears on the copper surface, but it is not silver. The solution gradually turns light blue, and there is a silver substance precipitated on the surface of the copper, and the solution gradually turns light blue.
