Acid could react with litmus in the acid and base indicator, turning the litmus test solution red. Acid could react with some metal compounds to form salt and water, but it would not directly form a red solution. Acid could react with metal to form salt and hydrogen, but it would not directly form a red solution. Acid could react with some salt to form new acid and new salt, but it would not directly form a red solution. Therefore, the reaction between acid and litmus easily formed a red solution.

The reaction of sulfuric acid with different solutions was different: - During the reaction between the solution of sulfuric acid and the solution of the solution of - The acid reacted with rust (mainly composed of iron dioxide), dissolving and removing the rust. After the reaction, the solution turned yellow. - When sulfuric acid reacted with iron trioxid, reddish-brown floccule precipitations were dissolved to form a yellow solution; when sulfuric acid reacted with copper trioxid, blue precipitations were dissolved to form a yellow-green solution; when sulfuric acid reacted with copper dioxide, black solid was dissolved to form a yellow-green solution. - Gas was formed when the acid reacted with the metal, and it reacted with the metal. When the acid reacted with iron, the solution turned light green and released gas. When the acid reacted with aluminum, gas was formed. - When the solution is dropped into a solution (not specified) and vibrated while dropping, it may start to drop without any phenomenon. When a certain substance in the solution is basically transformed into another substance, gas will start to escape continuously (because the composition of the solution is not specified, only one possibility is provided). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Esters can be subjected to a reaction of either acid or base. In an acidic environment, the ester's decomposition was irreversible, and sulfuric acid acted as a catalyst. Although the catalyst participated in the chemical reaction, its mass and chemical properties remained unchanged during the reaction, and it returned to its initial state after the reaction ended. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction between the two substances is: NaCl2 (aq) + H2O(l). In the reaction, the two substances react in water to form a solution of NaClCl2 and water. In terms of reaction conditions, the reaction temperature was usually at room temperature (20 - 25 ° C), the concentration of the reagents was usually 10% - 20%, and the reaction time was usually 30 - 60 minutes. However, it was important to note that in the chemical equation, the same ions often could not react with new substances. From the reaction equation, the original substance was still produced, so the reaction was not obvious. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When the iron reacted with the copper sulfuric acid solution, the surface of the iron layer would release a red substance, and the solution would turn from blue to light green and finally brown. This was because the copper sulfuric acid solution was blue and weakly acidic, so the reaction first corroded the iron and formed the iron ions. The iron ions solution was light green, causing the solution to change from blue to light green. At the same time, because the metal activity of iron was stronger than copper, a replacement reaction occurred. The copper ions in the solution were replaced and reduced to copper. The copper was red, and red substances were separated from the surface of the iron. Subsequently, the iron ions in the solution were unstable and would continue to be oxided into iron ions. The iron ions in the solution were brown, so the solution would turn from light green to brown. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The quality of the solution did not change when the diluted sulfuric acid reacted with the solution. There were two reactions between dilute sulfuric acid and NaOx. The reaction equations were: H_{2} SO4 + 2NaOx = Na_{2} SO4 + 2H2}O and H_{2} SO4 + NaOx = NaHSO4 +H_{2}O. The substances before and after the reaction followed the law of conservation of mass, and the mass of the solution remained unchanged. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between the two substances would produce a mixture of carbon dioxide and water. This reaction helped maintain the stability of the blood's pH. It had little effect on the blood's pH. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between lithium sulfuric acid solution and soda ash will produce lithium dioxide and soda ash. The reaction equation is: Li Chi SO2 + 2NaOx--> 2LiOx + Na Chi SO2. The lithium dioxide was a white deposit, and due to its low dissolution, it was easy to separate out, which would cause the reaction to move forward. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Under normal circumstances, the reaction between the two could not be carried out directly. Because the lone pair of electrons of the oxygen of the alcoholic group was coupled with the aromatic ring, the reaction activity was very weak, and it could not be used to catalyze the ester reaction with the acid. To synthesize the ester, the reaction of an acid acid or an acid ether with the ether was usually done. For example, the reaction between the ether and the ether was: C6H50H +(CH3CO) 2O = CH3COOC6H5 + CH3COON. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
Cyclohexene was added to the acidic solution of sulfuric acid, which would undergo an oxidization reaction. The carbon-carbon double bond would be broken and then be oxided into a starch group. During the reaction, the purple color of the solution of sulfuric acid would disappear. This was because cyclohexene was an aromatic, which had a reducing property. The carbon-carbon double bond in it was easily oxided by the strongly oxidisable, acidic, and acidic potassium Permanganate. When the potassium Permanganate was reduced in the reaction, the Mn (7) ion was reduced to Mn (7) ions of other valences, so the color of the solution became lighter until it disappeared. The reaction equation was: 5C6H10 + 8KMnO4 + 12H2SO4 =5 (HOCC (CH2) 4COON)+4K2SO4 + 8MnSO4 + 12H2O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
