Copper and iron replacement reaction
Iron could replace copper because iron was more mobile than copper. In the solution, iron and copper sulfuric acid can react to form iron sulfuric acid and copper. The reaction equation is: For example, if iron filings were placed in a copper chloride-based solution, the copper would be replaced, but the replaced copper would cover the iron filings that had not reacted. One could also design such a device: put a copper chloride-containing solution (or copper salt solution) in a large beaker, insert a pure iron as an pole, and insert a carbon rod in parallel as an pole. The iron would dissolve in the copper chloride-containing solution. The iron would become the negative pole, and the carbon rod would be the positive pole. The copper ions in the solution would obtain electrons on the carbon rod, and the solution would become FeCl3. Pure copper could be obtained on the carbon rod. If pure iron was used as the positive pole (connected to the positive pole of the direct current power supply), and a thin pure copper rod was used as the negative pole (connected to the negative pole of the direct current power supply), then the copper chloride-water solution would be electrolysed. The positive pole would be continuously consumed, and the thin pure copper rod would become thicker (because the copper ions would gain electrons before the iron ions at this time, and the water solution would become a FeCl2 solution). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Iron in Copper Sulphate
When the iron reacted with the copper sulfuric acid solution, the iron could replace the copper from the copper sulfuric acid because the iron was more active than the copper. The reaction equation was: FeSO2 = FeSO2 + Cu2, and the reaction phenomenon was that a red solid was separated from the iron surface. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Iron Copper Nitrate Reaction Sequence
When iron reacted with a mixed solution of copper nitrates and silver nitrates, iron would react with silver nitrates first. If there was excess iron, it would react with copper nitrates. The reaction equation was: According to the metal activity order table, the stronger the metal, the stronger the oxidization of the positive ion, and the stronger the ability to replace the metal. According to the metal activity order, H, Fe3, Cu3, so the reaction between iron and copper nitrates is after the reaction between iron and silver nitrates. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of iron and colorless copper sulfuric acid
The reaction between iron (Iron) and copper (CuSO2) is a substitution reaction. Iron is more mobile than copper, and copper can be replaced. The reaction equation is: FeSO2 = FeSO2 + Cu2. The reaction phenomenon was: red substance (copper) was deposited on the surface of the iron layer, because copper was a red metal with metallic luster; the solution changed from blue (the color of copper sulfuric acid solution) to light green (the color of FeSO2 solution), and finally to brown. This was because the iron ions in the solution were unstable and would continue to be oxided into iron ions, and the iron ions in the solution would appear brown. From the reaction principle, the copper sulfuric acid solution was blue and weakly acidic, so the iron was corroded first, forming a pair of iron ions. At the same time, because the metal activity of iron was stronger than that of copper, a replacement reaction occurred, and the copper ions in the solution were replaced and reduced to copper. Because iron was a solid, after it was immersed in the copper sulfuric acid solution, the reaction occurred on the surface of the metallic iron, so the copper produced by the reaction would adhere to the surface of the metallic iron. If the immersion area was not large enough, and the concentration of the copper sulfuric acid solution was very high, the chemical reaction would stop when it reached a certain degree. The copper attached to the surface of the iron would protect the iron, so that it could not continue to react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Iron Rain Copper Sulphate Reaction Phenomenon
The reaction between iron and copper sulfuric acid was that a red substance was deposited on the surface of the iron layer, and the solution changed from blue to light green and finally to brown. The chemical principle was that the copper sulfuric acid solution was blue and weakly acidic, so the iron was corroded first, forming the iron ions. The iron ions solution was light green, so the solution changed from blue to light green. At the same time, because the metal activity of iron was stronger than that of copper, a replacement reaction occurred. The copper ions in the solution were replaced and reduced to copper. Copper was red, so there was a red substance on the surface of iron. The reaction formula is: FeSO2 + CuSO2 = FeSO2 + Cu2. Subsequently, the iron ions in the solution were unstable and would continue to be oxided into iron ions. The iron ions in the solution were brown, so the solution turned from light green to brown. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction between iron and copper sulfuric acid solution
When the iron reacted with the copper sulfuric acid solution, the surface of the iron layer would release a red substance, and the solution would turn from blue to light green and finally brown. This was because the copper sulfuric acid solution was blue and weakly acidic, so the reaction first corroded the iron and formed the iron ions. The iron ions solution was light green, causing the solution to change from blue to light green. At the same time, because the metal activity of iron was stronger than copper, a replacement reaction occurred. The copper ions in the solution were replaced and reduced to copper. The copper was red, and red substances were separated from the surface of the iron. Subsequently, the iron ions in the solution were unstable and would continue to be oxided into iron ions. The iron ions in the solution were brown, so the solution would turn from light green to brown. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the reaction between copper sulfuric acid solution and iron?
The chemical equation for the replacement reaction between copper sulfuric acid solution and iron was: Iron was more mobile than copper. During the reaction, the surface of iron would be attached with red copper (metallic copper was a red metal with a metallic luster), and the solution would gradually turn from blue (blue for copper sulfuric acid solution) to light green (light green for iron sulfuric acid solution). During the reaction process, due to the weak acid nature of the copper sulfuric acid solution, iron was first corroded to form iron ions, and the color of the solution changed because of the light green color of the iron ion solution. At the same time, the copper ions in the solution were replaced by iron and reduced to copper, and copper adhered to the surface of the iron. Moreover, if the iron immersion area was not large enough and the concentration of the copper sulfuric acid solution was high, the reaction might stop at a certain level because the copper attached to the iron surface would protect the iron and prevent the reaction from continuing. In addition, the Fe2 + ions in the reacted Fe2 + were unstable and would continue to be oxided into Fe3 + ions. The Fe3 + ion solution would appear brown, and the solution might eventually turn from light green to brown. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the reasons for the reaction between carboric heating and copper sulfuric acid?
First of all, under normal circumstances, copper sulfuric acid itself did not react with carboric acid, but biuret reagent (a mixed solution of copper sulfuric acid and a large amount of excess NaOx solution) could detect the presence of an amine group, so it could also cause a color change with carboric acid. If the carboric acid was heated quickly, carboric acid would de-catalyze and trimerize into the six-membered ring compound cyanuric acid. Cyanic acid could react with copper sulfuric acid to produce a purple color. This was because copper sulfuric acid reacted with biuret to produce a purple color, which could be used to identify carboric acid. Cyanic acid might have a similar structure or reaction activity to biuret, resulting in a purple reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
