Copper could not undergo a substitution reaction with the metal. Because in the metal activity sequence table, the copper bar was weaker than iron, its reduction was weaker than iron, and the conductivity of the iron ion in the iron was weaker than that of the copper ion, so the two would not undergo a replacement reaction.

The chemical equation of the reaction between copper and copper is: Mn + CuSO2 = Mn + CuSO2 + Cu2. <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 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>
The double decomposition reaction between aluminum and sulfur could produce aluminum sulfuric acid, which was called NaAlSO4·12H2O. The reaction formula was: the reaction between aluminum and sulfur could produce aluminum sulfuric acid, which was called aluminum sulfuric acid. It was a colorless cubic octagonal crystal or white crystalline powder with a density of 1.6754 g/cubic centimeter. It was easily dissolved in water but not in alcohol. It was easily weathered in the air and lost 12 crystals of water when heated to become an anhydrite. It was widely used as a buffer, neutralizing agent, and solidifying agent in the food industry. It could also be used for refining sugar, as a raw material for swelling agents, and as a water purifying agent. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Under acidic conditions, the sulfuric acid would first react with the acid to produce the acid and water. After the sulfuric acid reaction was completed, the copper sulfuric acid would react with the acid to produce copper trioxide and the acid. The reaction phenomenon was that the solution became colorless and a blue deposit was formed. The reaction equation was CuSO4 + 2NaOx = CuOx + Na2SO4, and the corresponding ion equation was Cu2 ++2Ox- == CuOx. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
It wouldn't react because the elemental valences of copper dioxide and mercury dioxide were stable. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
BaSO4 does not react with NaOx, so there is no chemical reaction equation. Both of them did not have the conditions for metathesis and oxido-reduction reactions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
There was no reaction between the two. What happened between salt and salt was a double decomposition reaction, and the product should be two new kinds of salt. However, in order for the double decomposition reaction to occur, at least one of the two new salt should be a deposit. If the reaction between the salt and the salt occurred, the resulting salt and salt would be dissolved, so the two would not react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
During the reaction between the two, the original color of the solution would fade. Before the reaction, the solution may be purplish-black (elemental iodines are purplish-black crystals). Due to the oxidisation of iodines, it will undergo an oxido-reduction reaction with the reducing sodium-thionate (I <2>+2Na <2> S <2> O <2>= 2NaI+Na <2> S <2> O <2>). During the reaction, the iodines will be reduced, and the color of the solution will gradually fade until it disappears. If the solution was purplish-red due to air before the reaction, the purplish-red color would fade after the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Chromium-copper sulfuric acid solution can react, and the chemical equation of the reaction is 2Cr +3CuSO4 == Cr2(SO4)3 + 3Cu. In this reaction, the Chromium-copper solution is oxided to +3. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction is: SnO + CuSO4 + H2O = CuSO4 + CuSO4. The principle of the reaction was that copper ions were produced by the decomposition of copper ions into hydrogen ions, which then reacted with the metal. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
