Reaction Formula for Preparing Ferrous Oxides from Iron and Nitric Acid
The reaction of iron and sulfuric acid could not directly produce iron dioxide. Nitric acid has a strong oxidisation. When iron and sulfuric acid react, the sulfuric acid will catalyze iron into iron ions (Fe3) instead of iron ions (Fe2). The reaction equation is as follows: - The reaction of dilute sulfuric acid with a small amount of iron: Fe4 HNO2 (dilute) = Fe3 (NO2) 2 + NO2 + 2H2 O. - The reaction of dilute sulfuric acid with excess iron: 3Fe8HNO2 (dilute) = 3Fe2 (NO2) 2 + 2NO2 2 + 4H <2> O (but the iron ions formed here are easily further oxided to iron ions by sulfuric acid). The preparation of FeOx required the reaction of a solution of a Ferrous Salt (such as a solution of Ferrous Sulphate) with a solution of an Alkaline (such as a solution of NaOx). The reaction equation was: FeSO2 + 2NaOx = FeOx + NaOx. At the same time, in order to prevent the corrosion of the metal, the reaction usually needed to be carried out in an oxygen free environment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Formula of Magnesium and Dilute Nitric Acid
The chemical equation of the reaction between lithium and dilute sulfuric acid is: 3MG + 8HNO (dilute)== 3MG (NO) 2 + 2NO ^+4H2O; there is another reaction equation: MG +2HNO → MG(NO) 2 + H2O. <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>
Reaction Formula of Besium Hydride and Alkaline Sulphate
The reaction equation between BeOx and NaOx was: Be(Ox) 2 + 2NaOx = Na 2 BeO 2 + 2H 2 O. Besium hydrogen was an amphoric hydrogen dioxide, which could react with both strong acid and strong base, so it could react with the above reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Formula and Phenomenon of Divalent Ferric Acid and Iron
The iron in the iron chloride-ester was tri-valency, and there was no such thing as di-valency iron chloride-ester. The chemical equation for the reaction between iron and iron is: 2FeCl2 + FeCl2 = 3FeCl2. The phenomenon was that the iron powder gradually dissolved, and the solution turned from yellow to light green. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Esterification Reaction of Alcohol with Concentrate Nitric Acid
When the fermentation reaction between alcohol and concentrated sulfuric acid takes place, the reaction equation is: CH CH2-Ox + HO-NO <2>(concentrated H <2> SO2 <2>, heating) → CH CH2-O-NO <2>+ H <2> O. During the reaction, the alcohol degenerates the alcohol and the sulfuric acid dehydrogenates to form the ester of nitrates. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Law of Nitric Acid with Metal and Nonmetal
1. ** Reaction law of nitrates and metals ** - ** Passivation phenomenon **: Metal such as iron, aluminum, and aluminum are easily dissolved in dilute sulfuric acid, but they are not dissolved in cold concentrated sulfuric acid. This is due to the occurrence of a passive phenomenon. - ** Reaction with non-active metals ** - When the metal activity order table showed that the metal reacted with the metal after hydrogen, it could be seen that the metal was first oxided by the acid, and then the metal reacted with the acid to form nitrates. The main reduction product of concentrated sulfuric acid was NO2, and the main reduction product of diluted sulfuric acid was NO. For example, the reaction of silver with concentrated sulfuric acid: <2Ag +2HNO3 (concentrated)= Ag2O +2NO2 + H2O>,<Ag2O +2HNO3 = 2AgNO3 + H2O>, the total reaction is <2Ag +2HNO3 (concentrated)= AgNO3 + NO2 + H2O>; The reaction of silver with diluted sulfuric acid: <3Ag +4HNO3 (diluted)= 3AgNO3 +NO +2H2O>. - ** Reaction with active metals **: When sulfuric acid acts with the metal before hydrogen in the metal activity order table, in addition to the corresponding nitrates, the sulfuric acid may be further reduced to substances such as <anno data-annotation-id ="00000000 - 4000 - 4000 - 4000 - 8000 - 9000000000"></anno>,</anno>, and </anno>. In general, active metals react with concentrated sulfuric acid to form <anno data-annotation-id ="00000000 - 4000 - 4000 - 8000 - 8000 - 90000000000"> NO2 </anno>, dilute sulfuric acid to form <anno data-annotation-id ="0000000 - 4000 - 4000 - 9000 - 900000000000"> NO </anno>, and extremely dilute sulfuric acid to form <anno data-annotation-id ="20000a000000 - 90000000000"></anno></anno></anno>. For example, the reaction of calcium with different concentration of sulfuric acid: - \(Mg + 4HNO_3(16mol/L)=Mg(NO_3)_2+2NO_2↑+2H_2O\) - \(3Mg + 8HNO_3(6mol/L)=3Mg(NO_3)_2+2NO↑+4H_2O\) - \(4Mg + 10HNO_3(2mol/L)=4Mg(NO_3)_2+N_2O↑+5H_2O\) - \(4Mg + 10HNO_3(1mol/L)=4Mg(NO_3)_2+NH_4NO_3+3H_2O\) - \(5Mg + 12HNO_3(0.5mol/L)=5Mg(NO_3)_2+N_2↑+6H_2O\)。Moreover, the thinner the sulfuric acid was, the lower the valency of the nitrogen in the reduction product. However, it could not be mistaken that the dilute sulfuric acid had a stronger oxidisation ability than the concentrated sulfuric acid. In fact, the more concentrated the sulfuric acid was, the stronger the oxidisation ability was. - ** Special Metal Reaction **: Metal such as tin, stibine, and tungsten do not have much effect on nitrates. They may form an oxide-like substance that is not dissolved in nitrates, but they cannot form nitrates. 2. ** Reaction law of sulfuric acid and non-metals **: When sulfuric acid and non-metals react, it only shows the oxidisation property. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
