Under normal circumstances, the color of the hydrating ions of the iron ions was light purple. However, due to the strong tendency of iron ions to catalyze, the concentration of the ions was high, and it was commonly seen as a yellow or brown solution. In a strong acid environment, it can be inhibited from decomposing, and a light purple solution may be observed, but in reality, the phenomenon may be different due to a variety of factors (such as the presence of other impurity ions in the solution). Moreover, if it was iron chloride-diluted sulfuric acid, it would not react under normal conditions. If it was heated, it might produce iron sulfuric acid because of the crystallization of sulfuric acid. The reaction between iron and concentrated sulfuric acid was different. A small amount of iron reacted to form iron sulfuric acid, and a sufficient amount or excessive amount of iron reacted to finally form iron sulfuric acid. This was because after the concentration of sulfuric acid decreased to become diluted sulfuric acid, iron ions reacted with iron to form iron ions. Read more exciting novels for free
The reaction between iron and iron was that the iron gradually dissolved, and the solution slowly turned from brownish-yellow to light green. This was because the chemical valency of iron was zero, and the iron element in iron chloride-iron was positive tertiary. The iron and the positive tertiary iron ions in iron chloride-iron would undergo an oxidoreduction reaction, turning into positive secondary iron ions. The iron ions were light green, so the solution slowly turned from brownish-yellow to light green. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When iron reacted with sulfuric acid, the following phenomena would occur: iron gradually dissolved, the solution gradually turned light green, and bubbles were produced at the same time. This reaction was an exhalation reaction. This was because iron and sulfuric acid had a single substitution reaction. The chemical equation was: FeCl2 → FeCl2 + H2. The iron dioxide (FeCl2) formed in the reaction made the solution appear light green, and the hydrogen (H2) produced escaped in the form of bubbles. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The iron in the iron chloride-ester was tri-valency, and there was no such thing as di-valency iron chloride-ester. The chemical equation for the reaction between iron and iron is: 2FeCl2 + FeCl2 = 3FeCl2. The phenomenon was that the iron powder gradually dissolved, and the solution turned from yellow to light green. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between the two was the reaction between the two, and the equation was: [2Na_{2} O_{2}+2H_2} O = 4NaOx + O_{2}^. The reaction phenomenon was that a large number of bubbles were produced, and the gas produced could reignite the wooden strips with sparks. The temperature of the test tube wall increased, and the solution first turned red and then faded (if the phenylethylene was added to the water in advance). This was because the reaction generated oxygen and released a lot of heat. The resulting soda ash turned the phenylethanes red, but the soda dioxide was oxidisable and would cause the red solution to fade. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
No reaction, because the metal activity of iron is weaker than that of potassium, so there is no reaction between the two metals. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Iron reacted with concentrated sulfuric acid. If there was an excess of concentrated sulfuric acid, the reaction equation was: Fe6 HNO2 (concentrated)= heating = Fe3 (NO2)+3NO2 ^+3H2 O. If there is an excess of iron, the reaction equation is: Fe4 HNO2 (concentrated)= heating = Fe2 (NO2) 2 + 2NO2 2 + 2H2 O. [Phenomenon: The reaction produces reddish-brown gas (NO <2>), and the iron is gradually dissolved.] At the same time, the color of the solution may vary according to the relative amount of iron and sulfuric acid and the degree of reaction. If the solution is formed, it may be brownish-yellow, and if the solution is formed, it may be light green. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Sulfuric acid does not react with FeCl3, so the reaction equation and phenomenon summary table cannot be provided. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The principle of the reaction between the two was that there was a lone pair of electrons in the nitrogen atom. When the nitrogen atom reacted with the acid, the lone pair of electrons of the nitrogen atom formed a coordination bond with the hydrogen ion in the acid to form an aminium salt. Take the reaction between hydrogen and hydrogen as an example. The reaction phenomenon is the production of a large amount of white smoke. The ion equation of the reaction was: [NH3 + H^+ = NH4 ^+]. From a microscopic point of view, the lone pair of electrons on the nitrogen atom in the nitrogen atom combined with hydrogen ions to form an amine ion. From a macro point of view, the reaction of the reaction of the formation of small white solid particles, dispersed in the air to form white smoke. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between the two was as follows: the strip of lithium gradually dissolved and bubbles were produced. When the outer wall of the test tube was held by hand, it would feel hot. The bubbles produced during the reaction were hydrogen gas, the dissolving of the strip was due to the formation of a solution of potassium chloride-based solution, and the heat on the outer wall of the test tube was due to the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When iron reacted with enough diluted sulfuric acid, the following phenomena would occur: the solid would slowly dissolve, bubbles would be produced, the solution would gradually turn from colorless to light green, and the resulting gas would be able to burn, producing a light blue flame when burning. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
