What does the reaction principle of grease and acid mean?
The reaction between oil and acid was actually the decomposition of ester under acidic conditions. The reaction mechanism was the same as the acid catalyze reaction of the ester of acetate-ether (CH3COOC2H5)(CH3COOC2H5 + H2O=(acid catalyze, reversibility)= CH3COON + C2H50H). The ester would produce the corresponding acid and alcohol. From the perspective of molecular structure, the ester bond in the oil molecules was destroyed in an acidic environment, and the corresponding fatty acid and glycerine (glycerine) were formed after the break. This reaction was a irreversible reaction, and the reaction speed was usually relatively slow. Therefore, in the acid removal process of some oil refining equipment, the acid value could be removed by adding acidic substances to react with the acidic substances in the oil.

Reaction Principle of Acid and Nitrite
The principle of the reaction between the two substances was that the reaction between the two substances would produce NaCl2, H2O, NO, and NO2. The reaction equation was 2NaNO2 + 2HQ = 2NaCl2 + H2O + NO + NO2. This was mainly due to the fact that the nitrogen acid was unstable and would decompose quickly. Moreover, nitrogen acid was a weak acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Principle and Phenomenon of the Reaction between Acid and Acid
The principle of the reaction between the two was that there was a lone pair of electrons in the nitrogen atom. When the nitrogen atom reacted with the acid, the lone pair of electrons of the nitrogen atom formed a coordination bond with the hydrogen ion in the acid to form an aminium salt. Take the reaction between hydrogen and hydrogen as an example. The reaction phenomenon is the production of a large amount of white smoke. The ion equation of the reaction was: [NH3 + H^+ = NH4 ^+]. From a microscopic point of view, the lone pair of electrons on the nitrogen atom in the nitrogen atom combined with hydrogen ions to form an amine ion. From a macro point of view, the reaction of the reaction of the formation of small white solid particles, dispersed in the air to form white smoke. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Principle of the Reaction of the Formation of a Compound from an Acid to a Compound
The formation of protein from the protein was through dehydration condensation. In this process, the carbon group (-COCH) of one molecular group was linked to the carbon group (-CH <2>) of another molecular group. At the same time, a molecular water was removed to form a bond (-CO-CH <2>-). In this way, multiple molecular groups were linked to form a chain. The chain was further twisted and folded to form a protein with a certain spatial structure. <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 Principle of Hypobaric Acid and Layered Washing Liquid
When the hypochlorite-related components react with the laundry liquid, the source of hypochlorite-related components may be formed by the decomposition of the solution. When mixed with the washing liquid, it basically would not react with the main component of the washing liquid, the " surfacing agent ", but it would react with the softening component of the washing liquid, namely the benzylalcohol. An oxidization reaction would occur, and the benzylalcohol would be oxided to be benzylalcohol or even sulfuric acid, and at the same time, it would produce Cl2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Will the reaction of acid and base solution change color? What is the experimental principle?
The reaction between acid and base solution may change color, which can be judged by the different colors of the acid, base, and neutral solutions. The principle of the color change of the alkali-base indicator was that the alkali-base indicator was some organic weak acid or organic weak base. In the solution, they could be partially dissociated into the indicator's ions and hydrogen ions (or hydrogen ions). Due to the change in structure, the molecules and ions had different colors, so they would display different colors in different alkali-base solutions. For example, when the sulfuric acid concentration in the solution was reduced, it would turn red when the sulfuric acid concentration increased. When acid and base react, the solution's pH-value will change, which will cause the acid and base indicator to gain a proton and transform from basic to the conjugated acid, or lose a proton and transform from acid to the conjugated base. Due to the change of its structure, the color will change. This color change is a chemical change, because the acid and base indicator is generally an organic weak acid or weak base. They are weakly ionised in water. The added acid or base will be ionised to produce H or Oh, which will cause the combination of the two to move to the equilibrium of ionisation and dehydration. It caused the ratio of ions to substances in the original solution to change and present different colors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Illustration of the reaction principle of 13 grams of zincate and 200 grams of diluted sulfuric acid
The chemical equation of the reaction between the two metals is: Mn +2ClCl2 = Mn + Mn. In this reaction, from a microscopic point of view, the zinc-atom (Zn) loses its electron and becomes a zinc-ion (zn2), while the hydrogen ion (H) in the sulfuric acid gains an electron and becomes a hydrogen atom. The two hydrogen atoms combine to form hydrogen molecules (H). From a macro point of view, when 13 grams of zincate and 200 grams of diluted sulfuric acid react, every 65 parts of zincate by mass will react with 73 parts of hydrogen dioxide by mass, producing 136 parts of zincate by mass and 2 parts of hydrogen by mass. As the reaction progressed, the zinc-based particles would gradually dissolve, and due to the formation of hydrogen gas, a large number of bubbles would be observed, and heat would be released during the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction principle of the equation between iron and dilute sulfuric acid?
Under normal conditions, iron salt (such as FeCl3) would not react with diluted sulfuric acid because both sulfuric acid and sulfuric acid were strong acid, and the corresponding iron salt was easily dissolved in water. However, when heated, it would form Fe2 (SO4)3 due to the decomposition of the sulfuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
