How to judge whether a substance can react with acid or base
1. * * Reaction between acid and base **: Acid and base can produce salt and water through a neutralizing reaction.
2. * * Reaction between acid and basic oxygen, and reaction between base and acidic oxygen: Acid and basic oxygen, and reaction between base and acidic oxygen can also produce salt and water. The reaction between acidic and basic oxides can also produce salt. It could be concluded that when an oxide-acid or oxide-base reaction occurred, as long as one had the word "acid" and the other had the word "base", the reaction could occur.
3. * * Metathesis reaction between acid, base, and salt **: Not all acid, base, and salt can undergo metathesis reaction. Only when the two compounds exchanged their components would there be a precipice in the product, or gas would be released, or water would be formed, then the metathesis reaction would occur. When determining whether salt and salt, salt and base could react, in addition to whether the product met the conditions for the metathesis reaction, it also depended on whether the reagent was dissolved. If the reagents were all dissolved, then the metathesis reaction could take place. If one of the reagents was not dissolved, then the reaction could not take place.
4. * * Reaction of special substances with acid or base **
- Some metals, such as aluminum and aluminum, can react with both acid and base (such as 2AlAlCl3 + 3H2, 2AlCl3 + 3H2, 2AlAl
- * * Some non-metals **: For example, S, can react with alkali-based reactions (3S +6NaH =(A) 2NaS + Na2SO3 + 3H2O), and can also react with concentrated sulfuric acid (S +2H2SO4 (concentrated)=(A) 3SO2 ^+2H2O).
- * * Some amphobic compounds such as Al2O3 and ZunO can react with both acid and base.
- * * Some amphobic matrixes **: such as [AlCl3],[ZN (OH) 2], can react with both acid ([2AlCl3]+6H2O]) and base ([AlCl3]+6H2O]).
- * * Some of the compounds that can form a complex **: such as

Does liquid base react with liquid acid? Why? Why?
Liquid bases will react with liquid acid. This was because the liquid base usually contained a hydrogen ion (H), and the liquid acid usually contained a hydrogen ion (H). When the two met, the hydrogen ion and the hydrogen ion would combine to form water (H O). At the same time, the positive and negative ions in the liquid acid and the liquid base would combine to form a salt. This reaction process was called the acid base neutralizing reaction. For example, the reaction between sulfuric acid (HQ) and soda ash (NaOx) would produce NaCl2 and water, and the reaction equation was HQ + NaOx → NaCl2 + H2O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
A substance that reacts with organic chemistry and sulfuric acid
In general, almost all organic bases could react with sulfuric acid, such as amine compounds and the acid radical of weak organic acid (such as Na-aceto). Adding the gaseous hydrogen into alkynes and alkynes could lead to an addition reaction. Theoretically, it could also catalyze the aldol condensation reaction. The hydrogen could also undergo alfa-monoclorination with the keto, and 1,4 addition reactions with the alpha and beta unsaturated keto and aldol. The reaction of organic amine and sulfuric acid would produce organic salt, such as methylamine, lethylamin, propylamine, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of acid and acid base indicator
The chemical equation of the reaction between acid and indicator: KHIn/(H+)=(In-)/(HIn)=a/(a-c). Using litmus as an example, the equilibrium of the ions was HIn = In- + H+. However, it should be noted that the acid and base indicator will change color when it meets an acidic or basic solution. The actual color change is the acid and base indicator, not the solution itself. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Will sulfur and acid react?
Sulfur can react with a strong oxiding acid. For example, sulfur can react with concentrated sulfuric acid: S +2H <2> SO2 <2>(concentrated)= 3SO2 <2>+2H <2> O(under heating). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
It can react with the acid
The reaction equation for the reaction between the two substances is: 2C H SH + 2Na → 2C H ONa + H ^. Under normal temperature, the reaction of the two substances was solid. If the method of heating and melting the two substances and then adding the metal Na was used to carry out the experiment, the two substances would be easily oxided, and the color of the two substances would change when heated, which would affect the experimental results. However, if he dissolved the ether in it, the reaction between the two could proceed smoothly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can Acid Acid react with Barium Nitrate?
Both of them were compounds, and what happened between the two was a metathesis reaction. When an acid and a salt undergo a double decomposition reaction, the new salt formed is required to be a deposit. However, if the acid reacted with the calcium, the formed calcium was a dissolved salt, so the two did not react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The elemental substance that can react with hclnacl solution is
According to chemical knowledge, metals such as zincate (Zn) could react with hci, and the reaction equation was Zn +2hci = znci <2>+ H <2>. For NaCl solution, because of the strong mobility of the metal, it could not react with NaCl solution through a displacement reaction. However, metals such as metallic magnesium (mn) could react with hci but not NaCl. In addition, according to the information provided, elemental iron can react with strong acid, and as a strong acid, it can react with acid (FeCl2 + H2), but not with NaCl2. In addition, as mentioned in Material 3, C powder (non-metallic elemental substance) can be identified by strong acid, which also means that C powder does not react with HQ. In summary, the elemental substances that could react with HQ were metal elemental substances such as iron, while the NaCl-solution did not react with many elemental substances. The elemental substances that could react with HQ might not react with the NaCl-solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can the extracting agent react with the extracted substance?
What you want to ask is whether the extraction agent can react with the extracted substance. Generally speaking, the extraction agent could not have a chemical reaction with the extracted substance. The principle of extraction was to take advantage of the difference in the solute's dissolving rate in two different liquids. It was a method of extracting the solute from a solution composed of two different liquids. If the extraction agent reacted with the extracted substance, it would not be a simple extraction. It would become a chemical change to form a new substance, which would not meet the requirements of extraction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How does the sulfuric acid react with the sulfuric acid?
The reaction between the alcoholic group and the solution was an alkali-base reaction, which was accompanied by the protonation of the alcoholic group and the deprotonation of the solution. In the reaction, the hydrogen atom in the alcoholic group was replaced by the alcoholic group in the sulfuric acid, forming water and a positively charged ion. At the same time, the negative ion in the sulfuric acid combined with the positively charged ion in the alcoholic group to form a salt. The reaction equation was: <<p>><p></p>><p></p>><p><p>><p><p>><p><p>><p><p>><<p>><p> p>><p>> p> p>>& gt In general, because the alcoholic group was weakly acidic, it could react with the strong base, namely, soda. It did not require any special reaction conditions and could react at any time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
