Dilute sulfuric acid and naoh reaction solution quality
The quality of the solution did not change when the diluted sulfuric acid reacted with the solution. There were two reactions between dilute sulfuric acid and NaOx. The reaction equations were: H_{2} SO4 + 2NaOx = Na_{2} SO4 + 2H2}O and H_{2} SO4 + NaOx = NaHSO4 +H_{2}O. The substances before and after the reaction followed the law of conservation of mass, and the mass of the solution remained unchanged. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The image of the reaction of dilute sulfuric acid and dilute sulfuric acid
When the diluted sulfuric acid was slowly dripped into the solution of the soda, the reaction was heated up and the temperature gradually increased. The image showed that the temperature increased along the horizontal axis (the amount of diluted sulfuric acid added). When the reaction was completed, the temperature reached the highest value. After that, due to the heat loss when the reaction stopped and the cooling effect of the added diluted sulfuric acid, the temperature might gradually decrease. During the reaction process, the solution's pH-value kept changing. With the decrease of the amount of NaOx due to the reaction, the pH-value gradually decreased. When the reaction was complete, the pH-value was equal to 7, and when the diluted sulfuric acid was added, the pH-value was less than 7. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction rate equation of iron and dilute sulfuric acid
The chemical equation of the reaction between iron and dilute sulfuric acid was: FeSO2 = FeSO2 + H2. The reaction rate was affected by many factors, such as the concentration of the reagent, temperature, the surface area of the iron, and the presence of a catalyst. However, there was no specific equation called the " reaction rate equation of iron and dilute sulfuric acid " to describe the reaction rate. From the perspective of reaction rate theory, according to the effective collision theory, the reaction rate was related to the frequency of effective collisions between activated molecules. " For example, when the concentration increases, the number of molecules of the reagent in the unit volume increases, and the number of activated molecules also increases correspondingly. The effective collision frequency increases, and the reaction rate increases. When the temperature increases, the speed of the molecular movement increases, and the percentage of activated molecules increases. The effective collision frequency increases, and the reaction rate increases. The surface area of the solid iron increases, and the chances of contact between the reagents increase, and the reaction rate also increases. If there was a catalyst involved, the activation energy of the reaction could be reduced, allowing more molecules to become activated molecules, increasing the effective collision frequency and accelerating the reaction rate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Dilute sulfuric acid and iron powder heat reaction? Why will it change color?
Dilute sulfuric acid would react with iron powder. Dilute sulfuric acid had strong oxidisation, and the reaction with iron powder was more complicated. When there is an excessive amount of dilute sulfuric acid, the reaction equation is: Fe4 HNO2 = Fe2 (NO2) 2 + NO2 + 2H2O; when there is an excessive amount of iron powder, the reaction equation is: 3Fe8 HNO2 = 3Fe2 (NO2) 2 + 2NO2 + 4H2O. As for the color change during the reaction, it was due to the reaction producing different substances. During the reaction, the iron was oxided by the sulfuric acid to form iron nitrates or iron nitrates. Iron ions had a specific color in the solution. For example, iron ions generally appeared yellow or brownish-yellow in the solution, which led to the reaction system to change color. <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>
