Reaction Principle of Toothpaste and Iodine
The components of the toothpaste were composed of zinc-citrate, sodium-glyconate, and sodium-oh. These components could react with the iodine-like substance in the tincture to form the iodine-like substance. Generally, the iodine-like substance was only slightly pale yellow, so when the tincture was dripped into the toothpaste water and stirred, the color of the tincture would disappear.

Reaction of Iodine and Peroxidoxin
During the synthesis of the hormone, there was a close relationship between the reaction between the two. After the oral intake of iodines was taken up by the thyreoids, it was oxided to "active iodines" under the catalyze of thyreobin (TPo). Then, the "active iodines" combined with the Tyr residue on the thyreobin (TL) to form one iodoTyr and two iodoTyr. Two molecules of diiodoTyr were condensed into T4, and one molecules of diiodoTyr and one molecules of one iodoTyr were condensed into T3. When there is an excess of iodination, the excess iodination will compete with the persimmon, which may inhibit the activity of the persimmon, resulting in a decrease in the synthesis of the hormone. At the same time, it may also inhibit the release of the hormone, resulting in hypoplasia. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of ethanohol-iodine-soda
The reaction of alcohol with hydrogen dioxide and hydrogen dioxide will result in an iodoform reaction. The reaction equation is: CH CH ^O +3 NaIO3 = CHI +HCOONa+2NaOx +H ^O. The reaction results in the formation of iodoform (CHI), hydrogen dioxide (HCOONa), hydrogen dioxide (NaOx), and water (H ^O). The reaction mechanism was to react alcohol with a solution of iodine-based soda. Soon, there would be a clear pale yellow deposit, which was the separation of iodoform. The iodoform was a pale yellow crystal that was not dissolved in water. It also had a special smell and was easy to identify. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Sulfur Sulphate with Iodine
During the reaction between the two, the original color of the solution would fade. Before the reaction, the solution may be purplish-black (elemental iodines are purplish-black crystals). Due to the oxidisation of iodines, it will undergo an oxido-reduction reaction with the reducing sodium-thionate (I <2>+2Na <2> S <2> O <2>= 2NaI+Na <2> S <2> O <2>). During the reaction, the iodines will be reduced, and the color of the solution will gradually fade until it disappears. If the solution was purplish-red due to air before the reaction, the purplish-red color would fade after the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of toothpaste squeezing into water
The surface of toothpaste usually contains a surfacing agent. When the toothpaste is squeezed into water, the water molecules will form a thin layer on the surface of the toothpaste. This is a phenomenon of surface tension, which will cause the water droplets to form a spherical shape on the surface of the toothpaste instead of spreading out. Due to the effect of the surface active agent in the toothpaste, the force between the water droplets and the surface of the toothpaste would change, and the water droplets would float for a while. Moreover, there were chemical components in the toothpaste that would react with water to produce gas, pushing the small pieces of toothpaste to "swim" on the water surface. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Soda Ash and Iodine Steam
When the reaction between the sulfur dioxide vapor (I ^) and the soda ash (Na ^CO2) occurs, the chemical equation is I ^+Na ^CO2 = NaI+ NaIO2 (g). The principle was that the decomposition of the carbon dioxide was basic, and the hydrogen ions in the solution reacted with the elemental sulfur to form the hydrogen ions. As the hydrogen ions were consumed, the equilibrium of the decomposition of the carbon dioxide shifted to the right, and the concentration of carbon dioxide gradually increased until it became gas overflow. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction of Nicotine with Iodine and Iodide?
Nicotine (C H N Chi) will react with iodines (I Chi) and iodines (Ki). The py ring structure in the antagonist had a certain degree of basicity and could undergo an electropathic substitution reaction with iodines. The main function of the ki here was to provide iodines (I) to maintain a certain equilibrium state of the iodines in the reaction system. The reaction would produce some organic compounds, but the structure of the reaction product was more complicated and would be affected by the reaction conditions (such as temperature and the reaction conditions). Generally speaking, it would produce the iodinated product of the antagonist, as well as other by-products. However, this was a relatively complicated organic chemical reaction that required in-depth research and analysis in the laboratory to accurately determine the specific structure and composition of the product. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Principle of Allergen Reaction
Allergy reactions are caused by some people being overly sensitive to the substances (allergens) they come into contact with. When a sensitive individual comes into contact with a foreign, harmless substance (an allergy), the immune system will overreact and the body will produce a type of protein specific to the allergy. These IgE-bound to the high-affinity receptor on mast cells and basophils. When the allergy entered the body again and met with these bound molecules, the form of the immune receptor would change from a dimmer to a monolith. This change in form would lead to the exposure of the protein sites of the relevant signaling pathways, which would activate the downstream signaling pathways, causing allergic reactions such as vasodilation and bronchiectomy. In severe cases, it could cause allergic shock. In an allergic reaction, the affected organs or tissues will be infiltrated by a large number of inflammatory cells (especially those that are not activated), and a high concentration of IgE will appear in the serum. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Oxidation-reduction reaction of vic and iodine-solution
Vitamin C (C H O) had extremely strong reducing properties, and the solution of iodination had an oxidisation property. When the two were mixed, a oxidoreduction reaction would occur. The reaction equation was: C H O (vitamins C and Ascorbic acid)+I 2 = C H O (dehydrated Ascorbic acid)+2Hi. In this reaction, the carbon dioxide reduced the iodine-like molecules, causing the color of the iodine-like solution to change from reddish-brown to colorless and transparent. This was because the iodine-like molecules were reduced to iodine-like ions, which were colorless. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Biuret and protein reaction principle
The principle of the reaction between biuret and protein was that biuret could react with copper sulfuric acid to form a purple substance. This might be caused by the peptidic bond structure in the biuret molecules. The nitrogen atom of the peptidic bond would form a purple complex with Cu2 + ions. Because there was also a peptidic bond structure in the protein, such a reaction would also occur. We called the purple reaction between the compound containing the peptidic bond structure and copper sulfuric acid solution "biuret reaction". In other words, as long as the molecules contained a peptidic bond, this characteristic purple reaction would generally occur. It wasn't that biuret reacted directly with the protein, but the reaction between the peptidic bond in the protein and copper ions. It was the same reaction type as biuret and copper ions. It was a " biuret reaction." When carrying out experiments related to the biuret reaction, biuret reagent A was a strong base, and biuret reagent B was copper sulfuric acid. When using it, add A to the protein solution first, shake it up, and then add B. Strong base and copper sulfuric acid can denature the protein, but this does not affect the purple reaction, because the essence of protein degeneration is that the spatial structure is destroyed, causing it to settle and lose its physiological activity. However, the bond structure and the sequence of the protein chain are generally not destroyed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Principle of Acid and Nitrite
The principle of the reaction between the two substances was that the reaction between the two substances would produce NaCl2, H2O, NO, and NO2. The reaction equation was 2NaNO2 + 2HQ = 2NaCl2 + H2O + NO + NO2. This was mainly due to the fact that the nitrogen acid was unstable and would decompose quickly. Moreover, nitrogen acid was a weak acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
