Reaction Principle of Iron Hydride Colloids and Sulfuric Acid Forming Precipitations
The colloid particles in the colloid of iron trioxides were positively charged. When sulfuric acid was added to it, the sulfuric acid ions in the sulfuric acid would cause the positively charged iron trioxides to lose their charge. Due to the change in the electric charge between the particles, the repulsive force between the particles decreased, and the collision intensified, which led to the accumulation of the particles and the formation of iron dioxide. The chemical equation of the reaction is: [2Fe2SO4]= Fe2SO4]+6H2O. Read more exciting novels for free

Experimental Report on the Reaction of Dilute Sulfuric Acid and Natrium Hydride
|experimental procedure| experimental phenomenon| experiment conclusion| |--|--|--| |continuously dripping the sulfuric acid into a solution of sulfuric acid in the presence of phenothalin.| The red color of the solution gradually disappeared| The diluted sulfuric acid reacted with the soda, and the equation was as follows: HC1 + NaOx = NaCl2 + H2O. When the red color just disappeared, it meant that the added sulfuric acid had completely reacted with the solution of sulfuric acid. This was because the combination of the Oh in the solution of sulfuric acid and the H in the solution of sulfuric acid formed H O, causing the solution to gradually weaken until it was neutral.| |continuously dropping the solution of the solution| If a solution of NaH was added to the solution of NaH, the initial solution would have a pH-value of <7, and the pH-value would gradually increase with the addition of NaH. If a solution of NaH was added to the solution of NaH, the initial pH-value of the solution would be <7, and the pH-value would decrease with the addition of acid. When the reaction was complete and formed NaCl-water, the pH-value would be <7. When the acid was excessive, the pH-value would be <7.| By measuring the change of the pH-value, one could directly see the change of the pH-value of the solution during the reaction between diluted sulfuric acid and the solution of the solution of| <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of iron rust and sulfuric acid
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>
What is the reaction type of precipitations between calcium dioxide and sulfuric acid?
The chemical equation of the reaction between Ba(Ox) 2 and Na <2> SO2 <2> is Ba(Ox) 2 + Na <2> SO2 <2>= BaSO2 <2>+2NaOx, which is a metathesis reaction. The conditions for the metathesis reaction to occur are the formation of a deposit, gas, or water. This reaction can occur because of the formation of the deposit of BaSO2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The principle of the reaction between diluted sulfuric acid and soda is
The reaction between diluted sulfuric acid and soda is a neutralizing reaction. The principle of the reaction is that the hydrogen ions (H) in sulfuric acid combine with the hydrogen ions (H) in soda to form water (H O). The chemical equation is as follows: During the reaction process, with the addition of the sulfuric acid, the Oh in the solution of sulfuric acid would continuously combine with the H. If the solution of sulfuric acid was dripped with the sulfuric acid, the red color would gradually disappear due to the decrease of the Oh. When the red color disappeared, it meant that the added sulfuric acid and the solution of sulfuric acid had completely reacted. <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 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>
