What is the reaction of purifying the crude iodines?
The crude iodines contained ICl and Ibr (the elements I were both +1). Adding Ki to the crude iodines could produce a reduction reaction to purify the iodines. The combination price of the I element decreased from +1 to produce the simple substance of iodines, and the combination price of I in Ki increased, so this reaction was an oxido-reduction reaction.

What is the reaction between iodines and sulfuric acid?
During the reaction between the two, the solution may appear dark purple or dark blue at first due to the presence of the iodine-based reagent.(In the presence of the starch indicator, the iodine-based reagent will make the starch appear dark blue.) As the reaction progressed, the color of the solution gradually changed. When the reaction approached the end point, if there was a starch indicator, the solution would turn from blue to light yellow, and finally the blue color would disappear. After the reaction was complete, the solution would be colorless. This was because the reaction of the iodine-like reagent with the sulfuric acid would gradually consume the iodine-like reagent, causing the color of the solution to change as described above. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is there a reaction between sulfur dioxide and iodines? Why?
The reaction of the thiothiosulphate with the iodines. This was because the sulfur in the sulfuric acid was +2, which had a strong reduction property, while the elemental sulfur had a strong oxidization property, so the two could undergo an oxido-reduction reaction. The reaction equation was I2+ 2Na2S2O3 = 2NaI+ Na2S4O6. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What causes the reaction between iodines and thiothiosulfates?
If there was still starch in the solution, the color of the solution would suddenly change after the initial reaction. This was because of the small ion of thionate, which diffused quickly and reacted quickly with iodines. On the other hand, starch was a big molecular, which diffused slowly and reacted slowly. At the beginning, the iodines produced would react with the thiothiosulfuric acid first. Since this reaction produced a colorless substance, the solution would not change color even in the presence of starch. As the reaction progressed, the amount of thionate was very small and depleted. The generated iodines could only react with starch to form a dark blue substance, which caused the solution to suddenly change color. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Alum and Ferrate in Purifying Water
Alum was used to purify water because the colloid formed after the aluminum was dissolved in water had an absorption effect on impurities, which could cause impurities to settle and achieve the effect of purifying water. Ferrate water purification was produced by the decomposition of ferrate ions, which produced iron ions. Iron ions were used as sorcerers to absorb various negative and positive ions, which played a very good role in water purification. In the process of drinking water treatment, the comprehensive performance of the eight characteristics of fermentation, absorption, coagulation, settlement, sterilization, disinfection, color removal and odor removal was a new type of non-chloride-based high-efficiency water treatment agent. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What's the reaction between iodines and sulfuric acid?
When they were together, the acid could prevent the dissolution of the iodinated ion. Because the iodinated ion was a weak acid radical ion, it was easy to be dissolved and the reaction was acidic. According to the same ion effect, the addition of the acid could prevent the iodinated ion from being dissolved and prevent the iodinated solution from deteriorating. Iodine can react with strong oxiding acid: 2HClO+ I 2 = HIO+ HQ. Iodine cannot react with weak oxiding acid, let alone non-oxiding acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What kind of gas is formed by the reaction of propylethlene and iodines?
The reaction between the two will produce a gas called hydrogen iodinate (Hi). In this reaction, the hydrogen dioxide in the carbon dioxide had a hydrogen radical (-SH), which could undergo an oxidoreduction reaction with the hydrogen dioxide. In this reaction, the hydrogen dioxide gas would be produced. However, the specific reaction may also be affected by the reaction conditions (such as temperature, solution, etc.). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the effect of the reaction principle between elemental iodines and thiothiosulfates?
The principle of the reaction between elemental sulfur and sulfur dioxide was based on the oxido-reduction effect. In the reaction, the iodines were used as the oxidiser and the thiothiosulfates were used as the reducing agents. The sulfur atom in the sulfur dioxide is oxided, and the reduction reaction of the sulfur atom occurs. The reaction equation is: S O 2 + I → S O 2 + 2I. This reaction could be used in many application scenarios such as iodotitrations. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What kind of reaction does starch turn blue when it meets iodines?
The reason why the starch turned blue when it came into contact with iodines was mainly due to the reaction of forming clathrates. Amylose was a helicoid structure formed by the condensation of alpha glucose molecules. Each glucose unit had a hydrogen group exposed outside the helicoid. Iodine molecules interacted with these hydrogen groups and were embedded in the axis of the starch helicoid. This effect was called clathration, and the resulting substance was clathrate. In addition, there was also the effect of absorption. Previously, it was thought that the absorption of starch onto the iodine-like substance would shift the visible light absorbed by the iodine-like substance to a shorter wave-length. The brown iodine-like substance would turn blue, and the disappearance of the blue color after heating was thought to be due to the increase in molecular kinetic energy, causing the absorption. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction equation and reason for the formation of aromatic compounds in the crude oil fraction
The crude oil could not directly produce gasoline. The crude oil was separated into different boiling point ranges according to the boiling point of each component in the crude oil. It was mainly used to obtain light oil such as gasoline, diesel, and kerosene. The aromatic reforming product was converted to other chemical processes, such as aromatic reforming products, which could be obtained through a series of complicated separation, reaction, and treatment processes. There was no reaction equation for the direct production of gasoline from gasoline, because gasoline was not a reaction process for the production of gasoline. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
