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. Read more exciting novels for free
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>
Will iron and copper sulfuric acid react to form iron sulfuric acid? Why?
The reaction between iron and copper sulfuric acid would not produce iron sulfuric acid. When iron reacted with copper sulfuric acid, iron was more mobile than copper, and a replacement reaction occurred. The iron atom lost two electrons and became a Fe2 ion, while the copper ion (Cu2) gained two electrons and was reduced to a copper atom. The reaction equation was: FeSO = FeSO + Cu2, and the product was FeSO, not Fe2 (SO). This is because in this reaction, iron is mainly oxided to iron ions instead of iron ions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Does iron react with sulfuric acid to form iron sulfuric acid and hydrogen gas?
Iron and sulfuric acid react to form iron sulfuric acid (FeSO2) and hydrogen gas (H <2>) instead of iron sulfuric acid. The reaction equation is: Fe2 + H2 SO2 → Fe2 SO2 + H2. During the reaction, the iron surface was corroded by hydrogen ions (H) in sulfuric acid, forming hydrogen gas (H) and iron ions (Fe2). The iron ions combined with the sulfuric acid ions (SO2) to form FeSO2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Iron powder and diluted sulfuric acid react dangerously
In general experiments or normal operating environments, the reaction between iron powder and diluted sulfuric acid was not particularly dangerous. From the reaction process, the reaction between iron powder and diluted sulfuric acid would produce hydrogen and iron dioxide. The reaction formula is: FeCl2 + H2. When hydrogen met an open flame in the air, it would burn or even explode. However, this reaction was usually carried out in an open container. The hydrogen would quickly spread into the air. As long as it was far away from the source of the open flame, it would not cause an explosion. During the operation, if it was carried out according to the chemical experiment specifications, such as operating in a well-vented environment to avoid acid splashing (by slowly adding iron powder to avoid the reaction being too intense and causing acid splashing), this reaction was relatively safe. However, if the reaction was carried out in large quantities in a closed space, there might be a risk of explosion if the hydrogen gas continued to accumulate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of concentrated and diluted sulfuric acid with iron

Will there be bubbles when iron and diluted sulfuric acid react?
When iron reacted with diluted sulfuric acid, bubbles would be produced. The chemical equation of the reaction between iron and diluted sulfuric acid was: FeCl2 + H2. This reaction was a replacement reaction. The reaction between iron and sulfuric acid replaced hydrogen, which was produced in the form of bubbles. At the same time, the solution gradually turned light green and the iron gradually dissolved. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Iron and diluted sulfuric acid react to turn green
When iron reacted with diluted sulfuric acid, the solution would turn from colorless to light green. This was because iron and diluted sulfuric acid had a replacement reaction. The chemical equation was: FeCl2 + H2. The reaction produced iron dioxide (FeCl2), which made the solution appear light green. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How does copper sulfuric acid and diluted sulfuric acid react completely?
In secondary school, it was believed that copper sulfuric acid (CuSO2) and diluted sulfuric acid (HQ) did not react. However, from a theoretical point of view, if there was a reaction between the two (CuSO +2HQ = H ^(CuCl) + H ^SO), the solution would turn from blue to yellow-green. To judge the complete reaction, one could observe that the color of the solution no longer changed from blue to yellow-green and the color was stable. From the perspective of composition analysis, one could detect whether there was any residual copper sulfuric acid or sulfuric acid in the solution through chemical analysis. If the existence of copper sulfuric acid or sulfuric acid could not be detected, the reaction could be considered complete. However, under the knowledge system of middle school, whether this reaction was complete or not was not considered. <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>
