Reaction equation and phenomenon of excess iron and concentrated sulfuric acid
Iron reacted with concentrated sulfuric acid. If there was an excess of concentrated sulfuric acid, the reaction equation was: Fe6 HNO2 (concentrated)= heating = Fe3 (NO2)+3NO2 ^+3H2 O. If there is an excess of iron, the reaction equation is: Fe4 HNO2 (concentrated)= heating = Fe2 (NO2) 2 + 2NO2 2 + 2H2 O. [Phenomenon: The reaction produces reddish-brown gas (NO <2>), and the iron is gradually dissolved.] At the same time, the color of the solution may vary according to the relative amount of iron and sulfuric acid and the degree of reaction. If the solution is formed, it may be brownish-yellow, and if the solution is formed, it may be light green. Read more exciting novels for free
Reaction equation of concentrated and diluted sulfuric acid with iron
1. 铁与浓硝酸反应： - 常温下铁在浓硝酸中会钝化，不反应。 - 加热时，若铁少量：\(Fe + 6HNO_{3}(浓)=\triangle=Fe(NO_{3})_{3}+3NO_{2}\uparrow+3H_{2}O\); - 若铁过量：\(Fe + 4HNO_{3}(浓)=\triangle=Fe(NO_{3})_{2}+2NO_{2}\uparrow+2H_{2}O\)。 2. 铁与稀硝酸反应： - 若铁少量：\(Fe + 4HNO_{3}(稀)=Fe(NO_{3})_{3}+NO\uparrow+2H_{2}O\); - 若铁过量：\(3Fe + 8HNO_{3}(稀)=3Fe(NO_{3})_{2}+2NO\uparrow+4H_{2}O\)。 <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>
Phenomenal equation of heating reaction between iron and concentrated sulfuric acid
The chemical equation for the reaction between iron and concentrated sulfuric acid is: Fe6HNO2 (concentrated)= heating = FeNO2 + 3NO2 + 3H2O. The reaction phenomenon was that reddish-brown gas (NO <2>) was produced and the iron gradually dissolved. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the equilibrium phenomenon of the reaction equation of sulfuric acid and sulfuric acid?
There was no reaction between sulfuric acid and sulfuric acid, so there was no equilibrium of the reaction equation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation for preparing concentrated sulfuric acid and nitrogen gas
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 equation of the reaction between cuprous chlorideand concentrated sulfuric acid
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>
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>

Reaction equation and phenomenon analysis of lead aluminum and sulfuric acid
There is no such substance as lead and aluminum. You may want to ask about the reaction of meta-aluminum and sulfuric acid. When the amount of sulfuric acid is insufficient, the reaction equation is: NaAlO <2>+ HNO <2>+ H <2> O = AI (OR)+ NaNO <2>, which is a white deposit when the sulfuric acid is added. When the amount of sulfuric acid was sufficient, the reaction equation was: NaAlO <2>+4HNO <3>= NaNO <3>+ AI (NO <3>)<3>+2H <2> O. The phenomenon was that the white deposit disappeared when the sulfuric acid was added and shaken. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation and phenomenon summary of sulfur dioxide and sulfuric acid
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>
