When iron reacted with sulfuric acid, the following phenomena would occur: iron gradually dissolved, the solution gradually turned light green, and bubbles were produced at the same time. This reaction was an exhalation reaction. This was because iron and sulfuric acid had a single substitution reaction. The chemical equation was: FeCl2 → FeCl2 + H2. The iron dioxide (FeCl2) formed in the reaction made the solution appear light green, and the hydrogen (H2) produced escaped in the form of bubbles. Read more exciting novels for free
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>
No reaction, because the metal activity of iron is weaker than that of potassium, so there is no reaction between the two metals. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction between sulfuric acid and iron was: FeCl2 + FeCl2 + H2. The reaction produced hydrogen, which was a colorless gas. After the reaction, the solution of FeCl2 was light green. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
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>
If concentrated sulfuric acid was added, the sodium-phenate would be Sulfonated to produce a sulfuric acid. If diluted sulfuric acid was added, a large amount of sodium-phenate would produce a sulfuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction phenomenon was that water was formed, the color of the reaction solution became darker, and the liquid in the test tube separated into layers. On the surface of the saturated solution of soda, there was a colorless, transparent, water-resistant, and fruit-flavored oily liquid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When iron reacted with enough diluted sulfuric acid, the following phenomena would occur: the solid would slowly dissolve, bubbles would be produced, the solution would gradually turn from colorless to light green, and the resulting gas would be able to burn, producing a light blue flame when burning. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When iron was heated together with concentrated sulfuric acid, the reaction could occur because the heat destroyed the dense oxide-film on the iron surface. During the reaction process, gas would be generated and the iron would gradually be consumed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
