What are the reaction conditions for the industrial preparation of sulfuric acid? Video
The industrial preparation of sulfuric acid mainly has the following reaction conditions: 1. ** Reaction using nitrogen and air as raw materials ** - Firstly, using the Pt-Ru alloy mesh as a catalyst, the reaction was carried out in an oxidization furnace at 800 ° C. The reaction equation was: 4NH3 + 5O2 = catalyst, high temperature = 4NO +6H2O. - The generated NO will react with O2 to form NO2 when cooled, and the equation is: 2NO+O2 = 2NO2. - The NO2 is absorbed by water in the absorption tower and converted into sulfuric acid under the effect of excess O2 in the air. The highest concentration can reach 50%. The reaction equation is: 4NO2 +O2+ 2H2O = 4HNO3. - The 50% of the prepared sulfuric acid could be used as a water absorbing agent by using titanium or concentrated H2SO4. Distillation could obtain high concentration of sulfuric acid, or even more than 98% of "fuming" sulfuric acid. - During the production process, NO could be recycled to maximize the use of raw materials and reduce the discharge of NOX in the exhaust gas. The exhaust gas was generally absorbed by a solution of NaOx to produce an oxido-reduction reaction. 2. ** Reaction under mild conditions (new research result)** - The China Academy of Sciences Dalian Institute of Chemistry and Physics reported the direct conversion of air to nitrates under environmental conditions (25°C and 0.1 Pa) through a heterogenious and uniform electrochemistry pathway, which was mediate by the radical. Compared to the reversibility of the hydrogen at the negative pole, the conversion was carried out at a reduction potential of 0V, which could achieve a Farad efficiency of 25.37%, and had over 99% nitric-acid selectively.

What are the reaction conditions of phosphorous and sulfuric acid?
The reaction between phosphorus and concentrated sulfuric acid was an oxido-reduction reaction. The oxidisation of concentrated sulfuric acid was more obvious under heating conditions, so the reaction needed to be heated. This reaction condition indicated that the reaction was difficult to occur at room temperature or the reaction rate was extremely slow. By heating to provide energy to promote the reaction, the reaction between phosphorus and concentrated sulfuric acid could occur according to the chemical equation 2P +5H2SO4 (concentrated)= 5SO2 + 2H2O +2H3PO4. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction conditions of copper and concentrated sulfuric acid in the laboratory
The reaction between copper and concentrated sulfuric acid required heating. Under heating conditions, copper gradually dissolved and bubbles were formed. The gas produced could turn purple litmus red or the fuchsia solution faded. After cooling, the solution diluted and turned blue. The reaction equation was: CuSO4 + SO2 → +2H2O. At the same time, there are side reactions such as 5Cu +4H2SO4 (concentrated)(heating)= 3CuSO4 + Cu2S +4H2O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical reaction conditions of the reaction between iron and dilute sulfuric acid
The chemical reaction condition of the reaction between iron and diluted sulfuric acid was the presence of diluted sulfuric acid. In this reaction, iron reacted with dilute sulfuric acid to form FeSO2 and hydrogen. The chemical equation was: FeSO2 = FeSO2 + H2. The reaction phenomena included slow reaction speed, the formation of bubbles, the solution slowly turning from colorless to light green, and the gas generated in the reaction could burn and produce blue flames when burned. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of sulfuric acid and sulfuric acid
There was no reaction between Na2SO4 and CH3COH. Because the acid was weak and the sulfuric acid was strong, the reaction of the weak against the strong usually could not happen. Therefore, there were no reaction equations and reaction phenomena, so it was impossible to provide a summary in the form of a table. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction phenomenon of adding sulfuric acid to the preparation of FeCl3?
Ferric acid reacted with sulfuric acid to form a light green solution, which was because the product was a hydratable iron ion. If there was more of it, it would produce chloride-ions, and the solution would turn yellow. Moreover, the addition of sulfuric acid would suppress the decomposition of iron ions. The concentration of iron ions would increase, and the yellow color should be deepened. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction between industrial sulfuric acid and white wine?
Under normal circumstances, there would be no chemical reaction between sulfuric acid (HQ) and alcohol (the main component of white wine is alcohol, C Chi H Oh) under normal conditions, so there would be no reaction. However, under some special conditions, such as the presence of strong oxidisers, complex reactions may occur. The products will be more complicated and not typical, and it is difficult to describe the reaction phenomenon. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

从化学原理角度看，铁粉与稀硝酸反应主要涉及硝酸的氧化性以及铁的还原性。在常温常压下即可发生反应。 1. 当稀硝酸过量时： - 反应方程式为\(Fe + 4HNO_{3}=Fe(NO_{3})_{3}+NO↑ + 2H_{2}O\)。 - 这里硝酸体现强氧化性，将铁氧化为\(Fe^{3 + }\)，硝酸中的氮元素从\( + 5\)价被还原为\( + 2\)价的\(NO\)。 2. 当铁粉过量时： - 反应方程式为\(3Fe+8HNO_{3}(稀)=3Fe(NO_{3})_{2}+2NO↑ + 4H_{2}O\)。 - 过量的铁会与生成的\(Fe^{3 + }\)进一步反应，将\(Fe^{3 + }\)还原为\(Fe^{2 + }\)，最终产物为硝酸亚铁。 <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>
Reaction of concentrated sulfuric acid, concentrated sulfuric acid, and concentrated sulfuric acid
When the reaction of the solution of excessive amount of potassium moons and concentrated sulfuric acid was carried out, the pale yellow crystals of phosphorus moons would be formed. The reaction equation was: PO4 ^3- +12MoO4 ^2- + 3NH4^+ + 24H^+= (NH4)3(P(Mo12O40))·6H2O → +6H2O. This was the characteristic reaction for identifying phosphorus radical. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction type of sulfuric acid and sulfuric acid?
When mixed with concentrated sulfuric acid, due to the strong oxidisation of concentrated sulfuric acid, the sulfuric acid would be oxided to produce products such as phenodinone, and the color would turn orange to dark red. If the reaction was heated, it would be more complicated. In addition to the above products, due to the dehydration and water absorption of concentrated sulfuric acid, a water molecules would be removed from the molecules of the sulfuric acid to form substances such as diphenylethers, and some ester substances would also be formed. At the same time, the sulfuric acid reacted with the sulfuric acid to produce the sulfuric acid. In general, the reaction between the two substances involved various reaction types such as the oxidization reaction, the dehydration reaction, and the Sulfonation reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The chemical equation for the reaction between sulfuric acid and sulfuric acid is: 2H ^SO2 + Na ^SO2-> 2NaHSO2 + Na ^SO2 + H ^O. In this reaction, the phenomenon was summarized as follows: - The reaction was an exothermic reaction that would produce heat. - Due to the production of sulfur dioxide gas, there may be a pungent smell (if it can be observed under suitable experimental conditions). It should be noted that sulfuric acid and sulfuric acid are dangerous chemicals, and safety should be paid attention to when operating or observing related reactions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
