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.

过氧化钠与硫酸反应实际分两步进行,第一步反应为\(2Na_{2}O_{2}+2H_{2}O = 4NaOH + O_{2}\),第二步反应为\(2NaOH+H_{2}SO_{4}=Na_{2}SO_{4}+2H_{2}O\),总的反应方程式为\(2Na_{2}O_{2}+H_{2}SO_{4}=Na_{2}SO_{4}+2NaOH + O_{2}\)。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>
At room temperature, concentrated sulfuric acid would have a slow corrosive effect on the polythene, and at 90 - 100 ° C, concentrated sulfuric acid would rapidly erode the polythene, causing it to be destroyed or decomposed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Based on context alone The concentrated sulfuric acid could not be used for the preparation of hydrogen. Because hydrogen is an basic gas, concentrated sulfuric acid is volatile and acidic. When the two meet, a reaction will occur: <anno data-annotation-id ="cdf10000 - 4c00 - 4c10 - 4c10-a100-a11111110000"></anno>(the reaction phenomenon is to produce a large amount of white smoke), rather than being used to prepare hydrogen. The laboratory usually uses a solid mixture of lithium monium and lithium monium to heat up to prepare hydrogen. The reaction equation is [2NH4] Cl2 + CaCl2][2][3][4][4][5][6][7][8][8][9][9][ CaCl_{2}+2H_{2}O + 2NH_{3}\uparrow\)。 <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation for the reaction of cuprous chloride-concentrated sulfuric acid is: CuCl2 = H(CuCl2). There were also opinions that the reaction equation was cucl +2hci = h2(cucl3), and there were opinions that cuprous chlorideand concentrated sulfuric acid did not react. The reason why cuprous chloridecould be dissolved in concentrated sulfuric acid was because of the formation of a complex. The resulting solution should be colorless, but it often had a brown color when placed in the air. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In the reaction of preparing bromic ether, the first reaction was the reaction between concentrated sulfuric acid and the solution of the acid.(It can only produce bisulfuric acid, which can be referred to the reaction with NaCl2). The reaction equation is [H_{2} SO4}+ NaBr2 = NaHSO4 + Brr]. Then the formed [Brr] will react with alcohol. Under the conditions of concentrated sulfuric acid absorbing water and heating, the bromoether will be vaporized. The reaction equation is [Brr + CH3} CH2} 0H = CH3} CH2} Br2 + H2}O]. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The reaction of the two could be used in the laboratory to produce nitrogen.((NH4) 2SO4 + 2NaOx = 2NH3 ^+ Na2SO4 + 2H2O), the nitrogen gas can be used for many purposes, such as the catalyst of the nitrogen dioxide.(4NH3 + 5O2 = 4NO +6H2O) and other reactions;<(NH4) 2SO4>> can be used for double decomposition reaction with table salt to produce aminium chlorideand react with aluminum sulfuric acid to produce aminium aluminum. It can be used together with Boric acid to produce fire-resistant materials. Adding it to plating solution can increase the electrical conductivity. It is also a catalyst for food maroon color. It is also a nitrogen source for cultivating yeast in the production of fresh yeast. It is also used for dyeing auxiliary agents for acid dye and leather deashing agent. It is also used in beer brewing, chemical reagents, and battery production. There were also applications such as mining rare earths (about 5 tons of lithium sulfuric acid was needed for each ton of rare earth ore), and so on. The use of lithium sulfuric acid could be used to make soap, improve soil (improve soil with lime powder, and use organic fertilizers such as lithium sulfuric acid and lithium chlorideto alkalize the soil), etc. After the two reacted, they could play a certain role in these related industrial production or reaction processes. For example, in the production process with the participation of lithium sulfuric acid, if the reaction needed to participate in the reaction, the reaction of lithium sulfuric acid and lithium sulfuric acid could be used to produce lithium sulfuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
