Reaction of iron with a small amount and excess of diluted sulfuric acid
The chemical equation of the reaction between iron and dilute sulfuric acid was [FeS_{2} SO4]= FeS_{4}+H_{2}"uparrow". Regardless of whether the dilute sulfuric acid was small or excessive, the reaction phenomenon was that the solid slowly dissolved, bubbles were produced, and the solution gradually turned from colorless to light green. The resulting gas could burn, and when it burned, it produced a light blue flame. This was because the iron and diluted sulfuric acid had a replacement reaction. As long as there was diluted sulfuric acid in the reaction process, the reaction would continue. The reaction phenomenon would not change because of the amount of diluted sulfuric acid.

The excess iron reacted with the diluted sulfuric acid to form the sulfuric acid.
The reaction of excess iron with dilute sulfuric acid would not produce phosphorous acid. Iron reacted with excess dilute sulfuric acid to produce nitrogen dioxide and iron dinitrate. The reaction equation was 3Fe8HNO2 (dilute) = 3FeNO2 + 2NO2 + 4H2O. Nitric acid has a strong oxidisation. When it reacts with iron, its product is affected by the amount of iron, but it will not form phosphorous acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction equation of sulfuric acid and diluted sulfuric acid
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>
Reaction of Na with diluted sulfuric acid and sulfuric acid
The reaction between the dilute sulfuric acid and the sulfuric acid was very intense. The chemical properties of Na were very active. When it was placed in diluted sulfuric acid, Na would first react with water to form Na_2 and H_2. The chemical equation was 2Na +2H_2 O = 2Na_2 Sulfur and H_2. The resulting Na_2 would then react with diluted sulfuric acid. The chemical equation was 2Na_2 Sulfur and H_2 Sulfur = Na_2 Sulfur and 2H_2 O. When the solution was added to the acid, it would react with water to form hydrogen and hydrogen. At the same time, the hydrogen would react with the acid immediately. The chemical equation was 2Na +2HQ = 2NaCl2 + H ^. In short, the reaction between the two acids and the sulfur would produce hydrogen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of the bisulfuric acid and a small amount of dilute sulfuric acid
The reaction of hydrogen bionate and a small amount of dilute sulfuric acid will produce sulfuric acid and nitrogen dioxide. The reaction equation is: 2NaHSO3 + 2HNO3 → 2H2SO4 + 2NO + H2O. This was an oxido-reduction reaction. Sulfite ions in the bisulfuric acid had a reducing property. They were oxided by the nitrates in the dilute sulfuric acid to become sulfuric acid ions, and at the same time, the sulfuric acid was reduced to nitrogen dioxide. The essence of the reaction was: 3SO32- +2H + +2NO3- = 2NO ^+ H2O +3SO42-. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What does the reaction of excess iron and concentrated sulfuric acid mean?
The reaction between excess iron and concentrated sulfuric acid meant that the amount of iron was sufficient for concentrated sulfuric acid. From the nature of the reaction, iron and concentrated sulfuric acid would undergo a "passive" phenomenon at room temperature, that is, a dense oxide-film formed on the iron surface to prevent the reaction from proceeding further. However, the reaction could continue under heating and other conditions. When iron reacted with concentrated sulfuric acid, as the amount of iron increased (in excess), more iron would participate in the reaction. Iron reacted with concentrated sulfuric acid to produce products such as iron nitrates. If there was an excess of iron, the excess iron would further react with the generated iron nitrates to reduce the iron nitrates. The final product might contain both iron nitrates and iron nitrates. In addition, there would also be nitrogen dioxide gas produced during the reaction of iron and concentrated sulfuric acid. The reaction situation was relatively complicated and involved the process of oxido-reduction reaction. The valency of the iron element would change during the reaction. The chemical valency of the nitrogen element in the sulfuric acid would also change. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What substance can be formed by the reaction of diluted sulfuric acid and iron?
The reaction between diluted sulfuric acid and iron will produce iron dioxide and hydrogen. The chemical reaction equation is: Iron (iron)+ H ^SO2 (diluted sulfuric acid)= FeSO2 (iron dioxide)+ H ^(hydrogen). This was because diluted sulfuric acid was weak in its oxidisation. It could not be oxided to iron ions (+3Fe), but could only be oxided to iron ions (+2Fe). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
