Is the reaction between iron and diluted sulfuric acid a substitution reaction?
The reaction between iron and diluted sulfuric acid was a substitution reaction. In this reaction, iron (Fei) was a simple substance and diluted sulfuric acid (HQ) was a compound. After the reaction, a compound such as FeCl2 and a simple substance such as hydrogen (H) were formed. This met the definition of a substitution reaction, which was a chemical reaction in which a simple substance reacted with a compound to form another simple substance and compound. Its chemical equation is: FeCl2 + H2. Read more exciting novels for free
What kind of substitution reaction does the reaction of iron and diluted sulfuric acid belong to?
Iron was a simple metal, and diluted sulfuric acid was an acid. The two reacted to form iron sulfuric acid and hydrogen. In this reaction, iron replaced the hydrogen element in the diluted sulfuric acid. This reaction was a type of replacement reaction where a simple substance reacted with a compound to form another simple substance and another compound. Iron, as an active metal, replaced the hydrogen element in the acid. It was a replacement reaction between metal and acid. The reaction equation is: FeSO2 = FeSO2 + H2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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>
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 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. <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>
What is the reason for the reaction between iron powder and diluted sulfuric acid?
The chemical equation of the reaction between iron powder and dilute sulfuric acid is: 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. The reasons for this phenomenon were as follows: - Solid slowly dissolving: Iron will react with diluted sulfuric acid. Iron atoms will enter the solution and combine with sulfuric acid ions, causing the solid iron to gradually decrease, so the solid will slowly dissolve. - Air bubbles: During the reaction process, hydrogen gas (H <2>) is generated. The hydrogen gas escapes in the form of gas, so bubbles will be seen. - The solution gradually turned from colorless to light green: iron reacted with dilute sulfuric acid to form FeSO2. The solution of FeSO2 was light green. As the reaction progressed, the concentration of iron ions in the solution increased, and the color gradually turned light green. - The generated gas can burn, and when it burns, it produces a light blue flame. The generated hydrogen is flammable, and when it burns in the air, the flame is light blue. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of iron and sulfuric acid
The reaction between iron and sulfuric acid only forms the second iron ion, but not the third iron ion. The reaction equation is: FeCl2 +H ^. This was because the elemental iron was the reducing agent in the reaction. Even if it formed a tertiary iron, it would be reduced to a secondary iron. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of P-nitrotoluene and diluted sulfuric acid? Why?
P-nitrotoluene and diluted sulfuric acid can react. P-nitrotoluene was a kind of alcoholic compound, which was slightly acidic. When it reacted with diluted sulfuric acid, it would undergo an acidic reaction. According to the process of preparing p-nitrotoluene, the reaction between the salt of p-nitrotoluene (sodium-phenate) and diluted sulfuric acid would change the reaction liquid's pH. When the reaction liquid reached a certain pH-value (such as 2 - 3), the reaction would stop. This process was the process of converting p-nitrotoluene into p-nitrotoluene. The reverse process was the reaction of p-nitrotoluene with base to produce p-nitrotoluene. Therefore, it could be inferred that p-nitoluene could react with diluted sulfuric acid. The essence of the reaction was an alkali-base neutralizing reaction. P-nitrotoluene provided a electron, and the sulfuric acid ions in the diluted sulfuric acid combined with the electron. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
