What is the color reaction of copper sulfuric acid in water?
Copper Sulphate (CuSO) is a white powder. When water is added, it will undergo a hydrating reaction (CuSO +5H ^O CuSO·5H ^O). Due to the formation of copper ions, the white color of copper sulphate will turn into blue crystalline particles (copper sulphate). Its water solution (Copper Sulphate Solution) was sky blue and weakly acidic. Read more exciting novels for free
The reaction to form copper sulfuric acid
Anhydrous copper sulfuric acid can react with water to form copper sulfuric acid. After heating copper sulfuric acid to lose crystal water, it can be restored to blue crystal copper sulfuric acid if it is put into alcohol or water-containing organic matter. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the changes in the reaction phenomenon of copper sulfuric acid crystals with water?
When a small amount of water was added, blue copper decahydrate crystals would be formed; when excessive water was added, the crystals would dissolve and form a blue solution. <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>
Reaction equation of sulfuric acid and sulfuric acid
There was no reaction between Na2SO4 and CH3COH. Because the acid was weak and the sulfuric acid was strong, the reaction of the weak against the strong usually could not happen. Therefore, there were no reaction equations and reaction phenomena, so it was impossible to provide a summary in the form of a table. <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>

Why can the reaction of copper and sulfuric acid be acidic and basic?
The reaction process between copper sulphate and Na was more complicated. First of all, copper sulfuric acid was a strong acid and weak base salt. In an water solution, copper ions would undergo a reaction: $Cu^{2 + } + 2H_{2}O/rightlefttharpoons CuClO +2H ^{+}$. This reaction would make the solution acidic. When Na is added to the copper sulphate solution, the Na first reacts with water: $2Na + 2H_{2}O = 2NaOx + H_{2}. This reaction forms a strong base, which makes the solution basic. Then, the formed soda ash reacted with copper sulphate: $2NaOx + CuSO4 = CuOx = CuOx = CuOx. Therefore, in the reaction system of copper sulfuric acid and copper sulfuric acid, the two processes of the decomposition of copper sulfuric acid and the reaction of the reaction of the acid and water to form a base could reflect the acidic and basic properties. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
