The chemical equation of the reaction between the two substances is: NaCl2 (aq) + H2O(l). In the reaction, the two substances react in water to form a solution of NaClCl2 and water. In terms of reaction conditions, the reaction temperature was usually at room temperature (20 - 25 ° C), the concentration of the reagents was usually 10% - 20%, and the reaction time was usually 30 - 60 minutes. However, it was important to note that in the chemical equation, the same ions often could not react with new substances. From the reaction equation, the original substance was still produced, so the reaction was not obvious. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The main component of rust was iron dioxide (Fe2 O2), and there was no such exact compound as "rust monocrystal." According to the reaction between rust (Fe2 O2) and sulfuric acid (HNO2), the reaction equation is Fe2 O2 + 6HNO2 = 2Fe2 (NO2)+3H2 O. This reaction is not an oxido-reduction reaction because iron and nitrogen are in the highest valency state and cannot undergo oxido-reduction reactions. <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>
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>
