Reaction Formula and Phenomenon of Iodine and Dilute Acid of Peroxide-hydrogen
The reaction equation is: $H_{2}O_{2}+2HQ + I_{2}= 2HIO2HQ $. Phenomenon: Iodine (usually a purple-black solid) will gradually dissolve, and the color of the solution may change. Due to the formation of a new substance such as periodic acid (HIOA) in the reaction system, the solution may show a different color from the original solution of the original iodine-based substance (for example, it may change from a purple-black solution to a colorless or other light-colored solution. The specific color change will be affected by factors such as concentration). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical reaction conditions of the reaction between iron and dilute sulfuric acid
The chemical reaction condition of the reaction between iron and diluted sulfuric acid was the presence of diluted sulfuric acid. In this reaction, iron reacted with dilute sulfuric acid to form FeSO2 and hydrogen. The chemical equation was: FeSO2 = FeSO2 + H2. The reaction phenomena included slow reaction speed, the formation of bubbles, the solution slowly turning from colorless to light green, and the gas generated in the reaction could burn and produce blue flames when burned. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Why does the reaction formula of dilute sulfuric acid ion change?
When dilute sulfuric acid reacted with Na, the ion reaction would change depending on whether the Na was excessive or not. When there is no excess of Na, the ion equation of the reaction between Na and dilute sulfuric acid is 2Na +2H + = 2Na+ + H2. When there is an excess of Na, the reaction equations are Na + H2SO4 = Na2SO4 + H2 and 2Na +2H2O = 2NaOx + H2. This was because Na was an active metal that could react with the hydrogen ions in the acid. When Na was in excess, it could also react with water, resulting in different reaction processes, which were reflected in different ion equations. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Formula of Ferric Acid and Trivalent Iron
The iron element in FeCl2 was already +3, so there was no reaction between iron ions of the same valency. Therefore, there was no reaction between FeCl3 and iron, and there was no corresponding reaction equation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Formula and Condition of the Reaction of the Acid and the Acid
Under normal circumstances, the reaction between the two could not be carried out directly. Because the lone pair of electrons of the oxygen of the alcoholic group was coupled with the aromatic ring, the reaction activity was very weak, and it could not be used to catalyze the ester reaction with the acid. To synthesize the ester, the reaction of an acid acid or an acid ether with the ether was usually done. For example, the reaction between the ether and the ether was: C6H50H +(CH3CO) 2O = CH3COOC6H5 + CH3COON. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
