Why do you need a saturated salt solution to heat up the reaction?
During the heating process of the saturated salt solution, as the water evaporated, the concentration of the solution continued to increase (when it exceeded the saturated concentration). The free energy of the solution was higher than the free energy of the crystal, and the solution spontaneously changed towards the crystal, thus the solute crystallized. This was from the perspective of free energy change. In addition, in industrial salt production, such as seawater salt, the saturated salt solution after the preparation of the salt was introduced into the crystallization area to continue to be exposed to the sun. The water was evaporated by heating, and the salt crystals were separated. This was a common situation where the saturated salt solution was heated to obtain salt crystals.

Reaction equation of saturated salt solution on the negative pole
When the saturated salt solution was electrolysed, the hydrogen ions on the negative pole obtained electrons to generate hydrogen. The reaction equation was: 2H +2e = H ^. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of the solution of the saturated solution of the solution of
There was no reaction between the saturated solution of NaCl2 and the solution of NaOx. This was because it did not meet the conditions for a metathesis reaction (forming a deposit, gas, or water). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of carbon dioxide with a saturated solution of bis (oh, oh
When there is a small amount of carbon dioxide, the chemical equation of the reaction is: <anno data-annotation-id ="cd00004 - 4c52 - 4c50 - 4c50 - 9c5b0000000"></anno></anno>The principle of the reaction between the carbon dioxide and the lithium tritium in the lithium tritium saturated solution was the same as that of the ordinary lithium tritium solution. However, because it was a saturated solution, there might be phenomena such as the solid separation of lithium tritium or the solution being oversaturated during the reaction process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the solution reaction equation of salt and alcohol mixture?
Under normal conditions, salt (mainly composed of salt) and alcohol (mainly composed of alcohol) would not react together. There was no solution reaction equation. However, in theory, the reaction of NaCl2 + CH CH2 </anno> OH could produce Na ethanate and sulfuric acid, but this was only a theoretical situation. In reality, it would not react under normal conditions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of the solution with the solution
There were different opinions on whether or not the reaction between the two substances occurred. One view was that silver chloride-soda would react to produce silver-white silver silver precipitations and NaCl2, and the silver-white precipitations could easily be converted to brown silver oxide-soda. The other view was that the reaction could not be carried out because the reaction between base and salt required the salt to be dissolved, while AgCl2 was difficult to dissolve. <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>

Ferrocyanide could react with the reaction of the acid to form a deposit of the acid. This deposit could carry away or absorb interfering substances. It had a strong ability to remove protein, but its ability to remove color was poor. The main reaction phenomenon was the formation of the precipitations of the metal. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to distinguish the reaction phenomenon between physiological salt and diluted sulfuric acid solution
Saline was an water solution of NaCl2, and the reaction between diluted sulfuric acid (H <2> SO2) and NaCl2 was a metathesis reaction. This reaction will produce NaHSOand hydrogen ClCl2 gas. The reaction equation is: NaCl2 + H2SO2 = NaHSO2 + HCl2. Therefore, the reaction phenomenon was the formation of bubbles. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The corresponding reaction in the solution is
There were many reactions that could occur in the solution. The following were some common types: 1. ** Metathesis reaction **: Two compounds exchange their components to produce two other compounds. In essence, the two substances that undergo a metathesis reaction exchange ions with each other in the water solution, combining to form a difficult to be ionised substance (precipitations, gases, water, or weak ions), so that the ion concentration in the solution is reduced, and the reaction is carried out in the direction of the decrease in ion concentration. It can be summarized as AB + CD = AD + CB, such as salt-salt reaction, salt-base reaction, salt-acid reaction, and so on. 2. ** Substitution reaction **: The reaction of a simple substance and a compound to form another simple substance and compound. It is one of the four basic reaction types in chemistry, including the reaction of metal and metal salt, the reaction of metal and acid, etc. It can be summarized as AB + C = A + CB. For example, the reaction between metal and salt (solution)(such as the reaction between iron and copper sulfuric acid solution: 3. ** Complex reaction **: It will generate heat of complex. 4. ** Polymerisation reaction **: It will generate heat of condensation. 5. ** Solution Polycondensation Reaction **: The condensation reaction of a suitable catalyst in a solution state in a solution (including water). 6. ** Precipitation reaction **: For example, NaCl2 + AgNO3 = AgCl2 + NaNO3, etc. It is a case of metathesis reaction, and the reaction forms a deposit. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
