The chemical equation of the reaction between dilute sulfuric acid (HNO2) and lithium dioxide (Ba(Ox) 2) is: 2HNO2 + Ba(Ox) 2 = Ba(NO2) 2 + 2H O. From the perspective of the ratio of the number of moles, 2 moles of sulfuric acid and 1 mole of lithium dioxide reacted completely to form lithium dioxide and water. When the reaction reached neutral, it meant that the acid and the base had completely reacted. The reaction could be carried out according to the ratio of the chemical equation above.

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>
Both of them were compounds, and what happened between the two was a metathesis reaction. When an acid and a salt undergo a double decomposition reaction, the new salt formed is required to be a deposit. However, if the acid reacted with the calcium, the formed calcium was a dissolved salt, so the two did not react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The reaction between Ba(Ce) 2 and sulfuric acid (HQ) will produce hydrogen cyanide (HQ) gas. The reaction equation is Ba(Ce) 2 + 2HQ = BaCl2 + 2HQ. Barium cyanide is an extremely toxic substance. When exposed to high heat or acid, it will produce a highly toxic cyanide gas. When operating a reaction involving potassium cyanide, safety regulations must be strictly adhered to. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
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>
The reaction of hydrogen bionate and a small amount of dilute sulfuric acid will produce sulfuric acid and nitrogen dioxide. The reaction equation is: 2NaHSO3 + 2HNO3 → 2H2SO4 + 2NO + H2O. This was an oxido-reduction reaction. Sulfite ions in the bisulfuric acid had a reducing property. They were oxided by the nitrates in the dilute sulfuric acid to become sulfuric acid ions, and at the same time, the sulfuric acid was reduced to nitrogen dioxide. The essence of the reaction was: 3SO32- +2H + +2NO3- = 2NO ^+ H2O +3SO42-. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
