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>
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>

Flame Reaction Experiment of Na Salt
The flame reaction of the salt should not be difficult to do, but it was actually more troublesome because the flame color of the salt was yellow, and the flame of the alcohol lamp was mostly yellow due to the unclean wick of the lamp and the impure alcohol. Even if the flame was almost colorless (light blue), when a new iron wire (or a nickel-based wire, platinum-based wire) was placed on the outer flame, the flame would still be yellow at the beginning. It was difficult to tell whether the flame color was the color of the original alcohol lamp or the color of the salt ion. To clearly see the yellow flame of Na, you can use the following method: 1. Forceps-cotton-alcohol method: Take a small ball of cotton (cotton wool) with a pair of tweezers and absorb a little alcohol (95% alcohol). Squeeze the alcohol on the cotton dry, then dip the cotton in some salt or waterless soda powder (grind it into fine powder) and ignite it. 2. Iron wire method: - He took a thin iron wire, wiped one end with sandpaper, and burned it on the flame of the alcohol lamp until there was no yellow flame. - Dip the end of the wire in water and then dip it in some salt or powder of the Na2CO3. - Light up a new spirit lamp (the wick of the lamp is clean and the spirit is pure). - The iron wire dipped in the powder of the salt was placed on the tip of the outer flame to burn. At this time, there was a small yellow flame on the tip of the outer flame, which was the salt flame. For students 'experiments, since most alcohol lamps were not clean, it was difficult to see the tip of the flame. Instead, a steel wire stained with salt could be placed in any part of the outer flame where there was a blue flame to burn. If the yellow flame covered the blue flame, it could be considered that the yellow flame was the salt flame. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction of sprinkling salt on ants?
Salt was sprinkled on the ants. After eating salt, the ants would easily die of dehydration. This was because the salt had a certain effect on ants. <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.
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>
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>
Melting, melting, melting, how to distinguish
Melting refers to the phenomenon of a solid substance dispersing in a liquid and finally turning into a liquid mixture. Melting is often used in the context of literature. It refers to ice or snow turning into water due to temperature or sunlight. It can also describe a sentence that warms a person's heart. Melting is often used in physics. It refers to the process of heating a substance to a certain extent from a solid state to a liquid state. This process requires the absorption of heat, so it is beside the word fire. The novel " There's Snow in Kyokuboku " is equally exciting. Everyone is welcome to click and read it!
The reaction conditions between acid, base and salt in junior high school chemistry
1. ** Condition of the metathesis reaction ** - For acid + base = salt + water (neutralizing reaction), at least one of the acid and base involved in the reaction was easily dissolved in water. - Acid + salt = new acid + new salt. If the salt in the reagent is difficult to dissolve, then the product must be dissolved. The reaction between acid and salt is a metathesis reaction in an aquatic solution. The conditions for the metathesis reaction must be met.(There are precipitations, gas, or water). For example, when limestone (CaCO) is used to produce CO2 in the laboratory, only sulfuric acid can be used, because the CaSOformed by the reaction of CaCOand sulfuric acid is slightly dissolved and will cover the surface of CaCOto prevent the reaction from continuing. It is necessary to master the reaction of weak acid salt (such as Na <anno data-annotation-id ="0000004 - 4445 - 400a-400a-800000005e"> CO2 </anno>, CaCO) with strong acid (HQ, H </anno> SO, HNO), and the reaction to form BaSOand AgCl. - Alkali + salt = new base + new salt. The base and salt participating in the reaction must be water-dissolved, and there must be a hard-to-dissolve substance or a volatile base (NH2·H2 O) in the product. - Salt + salt = two new types of salt. The two types of salt participating in the reaction must be water-dissolved. If one of the products was a hard-to-dissolve salt, the reaction could proceed. 2. ** Reaction conditions of acid and basic oxygen ** - Strong acid (H <2> SO2 <3>, HNO2 <3>, and HC1) can react with all basic oxide-based compounds, while weak acid (H <2> CO2 <3>, H <2> S <3>, etc.) can only react with active metal oxide-based compounds. 3. ** Reaction conditions of acidic oxides and alkalites ** - Under normal conditions, acidic compounds can react with strong base solutions, but SiO2 needs to be heated to react with a solid form of NaOx (or a solid form of KhOx). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
