Iron or copper, sulfuric acid or silver, which one will react first?

The reaction between iron and copper sulfuric acid would not produce iron sulfuric acid. When iron reacted with copper sulfuric acid, iron was more mobile than copper, and a replacement reaction occurred. The iron atom lost two electrons and became a Fe2 ion, while the copper ion (Cu2) gained two electrons and was reduced to a copper atom. The reaction equation was: FeSO = FeSO + Cu2, and the product was FeSO, not Fe2 (SO). This is because in this reaction, iron is mainly oxided to iron ions instead of iron ions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

From the metal activity sequence table, it could be seen that copper was more active than silver. Nitric acid was a strong oxidistic acid, and it would react with metals with strong reducing properties first, which meant that it would react with copper first. Moreover, if silver reacted first to form silver nitrates, copper could reduce silver nitrates to silver and form copper nitrates. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

When iron reacted with the mixed solution of sulfuric acid and copper sulfuric acid, there was no problem of who reacted with iron first. This was because sulfuric acid and copper sulfuric acid were uniform solutions, and it was impossible to determine which iron would come into contact with first. This kind of mixture reaction was a competitive reaction. The iron would react with whichever ion it came into contact with first. Although Cu2 was more oxidisable than H, hydrogen could not reduce Cu2 in the water solution, so there was no order. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

When iron and copper sulfuric acid react, because iron is more active than copper, iron can replace copper ions in copper sulfuric acid. The reaction equation is: The reaction phenomenon was that a purplish-red substance (the color of copper) was separated from the surface of the iron layer, and the solution changed from blue (the color of copper sulfuric acid solution) to light green (the color of iron sulfuric acid solution). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Copper did not react with dilute sulfuric acid because copper was located after hydrogen in the metal activity sequence and could not replace the hydrogen in dilute sulfuric acid. However, copper and concentrated sulfuric acid can react under heating conditions, and the chemical equation is: Cu +2H ^SO (concentrated) CuSO + SO2 ^+2H ^O. In addition, in the process of wet smelting copper, copper dioxide reacted with sulfuric acid to form copper dioxide and water, and then copper dioxide reacted with iron to form copper and iron dioxide. This process indirectly reflected the conversion relationship between copper and sulfuric acid (copper was first converted into copper dioxide and then reacted with sulfuric acid). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There are several main methods to produce copper from copper sulfuric acid: 1. ** Substitution reaction **: The elemental copper can be replaced by a metal that is more active than copper, such as iron. Since the metal activity of iron is stronger than copper, iron can be added to copper sulfuric acid solution to replace copper, thus obtaining elemental copper. 2. ** Heat and then reduce **: First, heat copper sulfuric acid to form copper dioxide. Then, the copper dioxide and reducing agent will react at high temperature to form copper. 3. Electrolyze: Copper can be obtained by electrolysing copper sulfuric acid solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Under normal circumstances, carboric acid did not react with copper sulfuric acid. Because carboric acid was basic, it would not directly react with copper sulfuric acid to form a deposit or other new substances. However, when the biuret reagent was made by mixing copper sulphuric acid with a large excess of NaOx solution, it could detect the amine group in the ureas, which would cause a color change with the ureas. Moreover, the biuret that may be present in the ureas could react with copper sulphuric acid to produce a purple color, but this was not the reaction of the ureas itself with copper sulphuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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 can react with sulfuric acid. At room temperature, iron reacted with diluted sulfuric acid to form iron dioxide and hydrogen. The reaction equation was: When iron reacted with concentrated sulfuric acid, there were two situations: if the iron was in a small amount, the reaction product would be iron sulfuric acid, sulfur dioxide, and water under heating conditions. The reaction equation was 2Fe2 + 6H2SO2 = heating = Fe2 (SO2)+3SO2 (g)+6H2O; If the iron was sufficient or excessive, the final product would be iron sulfuric acid. The reason was that when the concentration of sulfuric acid was reduced to a certain level, it would become diluted sulfuric acid. At this time, the iron ions in the solution would react with iron to form iron ions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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>
