The reaction between the solid of sulfur dioxide and concentrated sulfuric acid is Na2S +2H2SO4 (concentrated) == S +2H2O + SO2 + Na2SO4. Read more exciting novels for free
When concentrated sulfuric acid was added to the solid of the sulfur dioxide, since the concentrated sulfuric acid had a strong oxidisation property and the sulfur dioxide had a reduction property, the two would undergo an oxidoreduction reaction. The reaction equation is [Na ^S + H ^SO (concentrated)= S + Na ^SO + H ^O]. The reaction phenomenon was the formation of sulfur, and at the same time, the formation of sulfuric acid and water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Elemental sulfur can undergo an oxido-reduction reaction with concentrated sulfuric acid under heating conditions. Sulfur is oxided to sulfuric acid with a +6 valency, and concentrated sulfuric acid is reduced to nitrogen dioxide with a +4 valency. The reaction equation is: S +6HNO= heating = H ^SO+ 6NO ^+2H ^O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction equation for the reaction between ethene and concentrated sulfuric acid was: CH2 = CH2 + H2SO4 → CH3CH2OSO3H. In chemistry, there was no reaction without heating or concentration, such as the reaction between carbon and concentrated sulfuric acid or concentrated sulfuric acid, the reaction between copper and concentrated sulfuric acid. The reaction between ethene and concentrated sulfuric acid was not mentioned. However, according to the laws of chemistry, ethene had a certain degree of reduction, and concentrated sulfuric acid had strong oxidization. Under certain conditions, the two could react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Sulfur dioxide ($SO2 $) and sulfuric acid ($H2SO4 $) had different reactions. If it was concentrated sulfuric acid, the reaction equation was: 2H2SO4 (concentrated)+ SO2 = 2H2O +3SO3. The phenomenon was that the pungent gas ($SO2 $) was absorbed by concentrated sulfuric acid, and a small amount of smoke might be seen during the reaction ($SO3 $might form acid mist in the air). If it was diluted sulfuric acid, it would basically not react. He could simply draw a picture with the reaction equation written on it and a small picture beside it to indicate the phenomenon of smoke production. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
You just gave it the name " Diagram of the kinetic change of sulfur dioxide to sulfuric acid reaction ". There's no more content. I can't reorganize it according to the requirements.

The reaction between diluted sulfuric acid and sulfur dioxide produces water, nitrogen dioxide gas, and sulfur precipitations. The reaction equation is: 8HNO +3Na ^S = 4H ^O + 2NO ^+6NaNO + 3S. The reaction between concentrated sulfuric acid and sulfur dioxide produces water, nitrogen dioxide gas, and sulfur precipitations. The reaction equation is: 4HNO + Na ^S = 2H ^O + 2NO ^+ 2NaNO + S. However, there was also a view that the reaction could not produce sulfur and sulfur. Instead, it would produce either sulfur and sulfur, or sulfur and water, or other nitrogen and oxygen compounds. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction between concentrated sulfuric acid and copper dioxide is CuO +2HQ = CuCl2 + H2 O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The nitrogen dioxide did not react with the dilute sulfuric acid, nor did it react to form carbon dioxide. The chemical formula of nitrogen dioxide was NO. It usually did not react with dilute sulfuric acid, and the reaction would not produce carbon dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Sulfur dioxide (<anno data-annotation-id ="00000100 - 4c00 - 4c00 - 4c00-a000 - 5c0000b00000"> SO2 </anno>) and hydrogen dioxide (<anno data-annotation-id ="0000000 - 4c00 - 4c000000000"> H2O2 </anno>) will react with the reaction equation of <anno data-annotation-id ="0000000 - 4000 - 4c0000000000000"> SO2 + H2O2 = H2SO4 </anno>. The reaction principle was based on the strong reducing properties of sulfur dioxide and the strong oxidisation properties of hydrogen dioxide. At room temperature, the two would undergo an oxido-reduction reaction and eventually combine to form sulfuric acid. In the experiment, the required materials were sulfur dioxide, hydrogen dioxide, iron frame, test tube, rubber head dropper, etc. However, due to the slow reaction rate and the acidic solution after the reaction, the oxidization ability of hydrogen dioxide was weakened under acidic conditions. It was not recommended to use this reaction method to absorb sulfur dioxide when dealing with sulfur dioxide.(For example, in the laboratory, sulfur dioxide is generally absorbed with a solution of soda. In the industry, sulfur dioxide in the tail gas is generally absorbed with lime water. Sulfur dioxide with higher purity is produced by oxygen in the presence of a catalyst, and then absorbed with concentrated sulfuric acid.) <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Acetic anhydryride-concentrated sulfuric acid reaction (Liebermann-Burchard reaction) can be used to identify tripenoid and steroid side. The specific identification method was as follows: dissolve the sample in vinegar and add concentrated sulfuric acid-vinegar (1:20). If the final color was red or purple, it was triterpene soap. If the final color was blue-green, it was steroid soap. During the reaction process, color changes such as red → purple → blue → green → dirty green would occur in turn, and finally the color would fade. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
