The Microscopic Essence of the Reaction between Salt and Natrium Carbonic Acid
For the reaction between carbon dioxide and some salt, take the reaction between carbon dioxide and calcium chlorideas an example. The microscopic essence is the combination of carbon dioxide ions and calcium ions to form a calcium dioxide deposit. From the perspective of ions, it was the combination of the positive and negative ions in the solution to form a deposit, which pushed the reaction in the positive direction. In the reaction of the acid with other salt, the microscopic substance was also the combination of the ions in the solution to form a deposit, allowing the reaction to occur.

Reaction Formula of Carbonic Acid and Salt Salt
Carbonic acid does not react with NaCl3. According to the possible reactions, NaCl2 + H2CO2 = NaHCO2 + HQ or 2NaCl2 + H2CO2 = Na CO2 + 2HQ, this was a weak acid making a strong acid, which was impossible to happen. Moreover, the reverse reaction of these two equations could be carried out to eventually produce NaCl2, H2O, and CO2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Essence of the Reaction of Salt and Salt
氯化铵与氢氧化镁反应的实质可从以下方面分析。氯化铵是强酸弱碱盐，在水中发生水解产生氢离子，即\(NH_{4}^{+}+H_{2}O = NH_{3}\cdot H_{2}O + H^{+}\)。氢氧化镁难溶于水，但氢离子能与氢氧化镁中的氢氧根离子反应，即\(Mg(OH)_{2}+2H^{+}=Mg^{2 + }+2H_{2}O\)，从而促使氢氧化镁溶解。 从另一个角度看，这一反应也可理解为氢氧化镁沉淀能溶解于铵盐中。因为铵盐（如氯化铵）存在时，铵根离子与氢氧根离子结合，使氢氧根离子浓度降低，例如\(MgCl_{2}+2NH_{4}OH \rightleftharpoons 2NH_{4}Cl + Mg(OH)_{2}\downarrow\)这个可逆反应，当氯化铵大量存在时，平衡向左移动，沉淀溶解。此外，该反应也有气体生成推动反应进行的因素。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>

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>
What is the reaction of salt in lead-acid batteries?
The use of salt in lead-acid batteries would cause the concentration of sulfuric acid to decrease, thereby reducing the capacity of the battery. To be specific, adding salt would cause the lead sulfuric acid in the battery to crystalize, forming large crystals that were difficult to dissolve, causing the battery capacity to decrease or even be scrapped. Therefore, adding salt would have a negative impact on the lead-acid battery and could not be repaired.
What is the phenomenon of the esterfication reaction between the acid and the salt?
Instead of an esterfication reaction, a substitution reaction would occur between the two. The concentration of hydrogen ions in the water was still higher than that of water, and the reaction was quite intense. The density of the Na was lower than that of the Acetic acid. The Na floated on the surface of the Acetic acid and melted into a small ball. It kept jumping and gradually became smaller before finally disappearing. The reaction produced Na Acetic acid and hydrogen gas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to judge the reaction between diluted sulfuric acid and salt water
Dilute sulfuric acid and salt water did not react. Dilute sulfuric acid was an acid, and it was acidic. Salt water was an water solution of NaCl3. When the two were mixed, no new substance would be formed. Therefore, there was no such thing as a reaction, and there was no way to judge the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the change in the image of the reaction between metal and acid, base and salt
1. ** Reaction of metal and acid (horizontal coordinate is reaction time, vertical coordinate is hydrogen mass)** - In terms of reaction speed, the greater the slope, the faster the reaction speed. The order of metal activity can be determined according to the inclination of the curve. The greater the inclination, the stronger the metal activity. - In terms of hydrogen production: - When the metal is in excess and the acid (of the same concentration) is insufficient, the quality of the hydrogen produced is determined by the quality of the acid. At this time, the quality of the hydrogen produced by different metals is equal. - When the acid (with the same concentration) is sufficient, the quality of the generated hydrogen is determined by the quality of the metal, and the relationship is as follows: 2. ** Reaction between metal and acid (x-axis is the mass of acid, y-axis is the mass of hydrogen)** - The situation was different in different areas: - When 0 < m <a (excessive or just complete reaction, iron, magnetism, and aluminum are all excessive), the quality of the generated hydrogen has a specific situation (it needs to be judged according to the specific reaction data, such as the chemical relationship between the metal and the acid reaction). - When a < m <b (insufficient amount of iron, excessive amount of iron or just complete reaction, excessive amount of aluminum and aluminum), the quality of the generated hydrogen gas also has a corresponding situation (also needs to be judged according to the specific conditions of the reaction). - When b < m <c (there is insufficient iron and iron, excessive or just complete reaction of aluminum), the quality of hydrogen produced also has a corresponding situation. 3. ** Reaction between metal and acid (x-axis is the mass of metal, y-axis is the mass of hydrogen)** - At the beginning of the reaction, the metal was insufficient and the acid was excessive. The quality of the hydrogen produced was determined by the metal. - As the metal continued to increase, the amount of metal would not be enough, and the quality of the hydrogen produced would be determined by the acid. 4. ** Reaction between metal and salt solution (Take the reaction between a piece of metal and a solution of copper sulfuric acid as an example, from the perspective of solid and solution quality)** - Solid mass change: During the reaction, the solid mass changes from 65 (relative atomic mass of copper) to 64 (relative atomic mass of copper). The solid mass decreases. After the reaction, the solid mass remains unchanged. - Change of solution mass: The solute mass changes from 160 (relative molecular mass of copper sulfuric acid) to 161 (relative molecular mass of sulfuric acid). The mass of the solution increases while the mass of the solution remains unchanged. After the reaction, the mass of the solution remains unchanged. 5. ** Reaction between metal and salt solution (Take the reaction between copper sheet and silver nitrates solution as an example, from the perspective of solid and solution quality)** - Solid mass change: The mass of the solid changes from 64 to 216 (the relative atomic mass of silver). The mass of the solid increases. After the reaction, the mass of the solid remains unchanged. - Change of solution mass: The solute mass changed from 340 (relative molecular mass of silver nitrates) to 188 (relative molecular mass of copper nitrates). The mass of the solution decreased while the mass of the solution remained unchanged. After the reaction, the mass of the solution remained unchanged. In short, the image change of the reaction between metal and acid, base, and salt involved many factors such as the reaction rate and the quality of the resulting substance. It was closely related to the activity of the metal and the amount of the reagent (the amount of metal and acid or salt solution). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the microscopic and microscopic characteristics of the reaction between hydrogen and oxygen?
** 1. macro characteristics ** 1. ** Phenomenon ** - When hydrogen was burned in oxygen, it would burn quietly and produce a light blue flame (when hydrogen was burned in the mouth of the glass tube, the flame was often slightly yellow). - A dry and cold beaker was placed above the flame. Water droplets would appear on the inner wall of the beaker, indicating that a new substance, water, had been formed. - The reaction process was accompanied by the phenomenon of light and heat. This was the performance of chemical energy being converted into heat and light energy. 2. ** Material Change and Energy ** - In terms of material changes, hydrogen and oxygen reacted to form water, which was a new substance. The reaction equation was 2H2 + O2→ 2H2O. - In terms of energy, the reaction released a large amount of heat. For example, rockets used the thrust generated by the reaction of liquid hydrogen and liquid oxygen (or solid hydrogen and solid oxygen) to fly. The hydrogen fuel cell also used the reaction of hydrogen and oxygen to produce water, electricity, and heat. The whole process was quiet, non-polluting, and completely carbon-free. The battery efficiency was 2 - 3 times higher than fossil fuel combustion, and the energy conversion efficiency could reach 80 - 90%. ** 2. Microscopic features ** 1. ** At the molecular level ** - From a microscopic point of view, hydrogen was made up of hydrogen molecules (H <2>), and oxygen was made up of oxygen molecules (O <2>). During the reaction, every two hydrogen molecules and one oxygen molecules would react. The chemical bond between them would break, and the atoms would reassemble to form two water molecules (H <2> O). 2. ** Atomic level ** - During the reaction, the number of hydrogen and oxygen atoms remained unchanged. Before the reaction, the hydrogen and oxygen atoms existed in the form of hydrogen and oxygen molecules. After the reaction, they combined to form water molecules. This was in line with the law of conservation of mass, which meant that in a chemical reaction, the sum of the masses of the substances participating in the reaction was equal to the sum of the masses of the substances formed after the reaction. From a microscopic perspective, the type, number, and mass of the atoms before and after the reaction did not change. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
