When iron reacted with dilute sulfuric acid, the reaction equation was: FeSO2 + H2SO4 = FeSO4 + H2SO4. The reaction phenomenon was usually the slow dissolution of the solid, the production of bubbles, the solution gradually turning from colorless to light green, and the resulting gas could burn, producing a light blue flame when burning. If there was too much iron, the reaction would still produce bubbles, and the solution would turn light green. The excess iron would remain in the reaction system because iron would react with diluted sulfuric acid to produce iron and hydrogen, and iron would not continue to react with the generated iron. As long as there was still sulfuric acid left, it would continue to react to produce hydrogen until the sulfuric acid was consumed. Read more exciting novels for free

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>

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>

When the three metals, namely, titanium, titanium, and iron, reacted with the acid, the order of activity of the metals was as follows: titanium, and titanium. Under the same conditions, when it reacted with the same concentration of sulfuric acid, the reaction phenomenon was also different. The reaction between titanium and sulfuric acid quickly produced a large number of bubbles and released a lot of heat; the reaction between titanium and sulfuric acid produced bubbles and released heat; the reaction between iron and sulfuric acid slowly produced bubbles, and the solution changed from colorless to light green. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
