    First of all, it is important to understand that water is a weak electrolyte that ionizes trace amounts of hydroxide and hydrogen ions.

    Whereas, hydrolysis and ionization can be seen as reciprocal.

    The essence of hydrolysis is that the ions ionized by the solute react in the direction of the hydroxide ions or hydrogen ions ionized by the water in the direction of producing a weaker electrolyte, and this reaction is weak and reversible.

    Central law, remember, chemical reactions in solution are directed towards the production of a weaker electrolyte (which is important).

    The decision to reflect the direction of superhydrolysis or to proceed in the direction of ionization depends on whether a weaker electrolyte can be generated.

    Like what. Sodium bicarbonate, carbonic acid is a weak acid, carbonic acid will not be fully ionized, so there will be bicarbonate in the sodium carbonate solution, so there are bicarbonate ions and sodium ions in the sodium carbonate solution, and the trace amount of bicarbonate in the solution and the weak hydrogen ions ionized in the water will produce a trace amount of carbonic acid, because carbonic acid is a weak acid, but also a weak electrolyte, ionization is very weak, so the reaction will proceed in the direction of producing carbonic acid. So the bicarbonate binds a small amount of hydrogen ions, leaving the hydroxide in the water, so it is alkaline.

    In sodium bisulfate solution, because sulfuric acid is a strong acid, all ionized, bisulfate will not exist, sodium bisulfate will also be fully ionized, sodium ions, hydrogen ions, sulfate ions. Because sulfuric acid is a strong acid, all ionized, (weak acid is partially ionized), so sulfuric acid will not combine with hydrogen ions to form sulfuric acid, (it can be understood as an explanation of instantaneous combination, because it is a strong acid, so it is all ionized immediately), and there is no weaker electrolysis generated, so it will not react in this direction, so there are still a large number of hydrogen ions in it, so it becomes acidic.

    For middle school students: sulfuric acid is a dibasic strong acid, two hydrogen ions can be fully ionized, because there is no weak acid group, so NaHSO4 is only ionized and not hydrolyzed.

    h2so4=2(h+)

    so4)2-

    Fully ionized.

    nahso4=(na+)

    h+)(so4)2-

    Fully ionized.

    For college students: sulfuric acid is a strong acid of one element, H2SO4 = (H+) (HSO4)-

    Fully ionized. But the second step is hydrolysis.

    hso4-)

    H+)(SO4)2- occurs only.

    Left and right, i.e., (SO4(2-)) are weak acid groups, so NaHSO4 is ionized out (SO4(2-)) and then hydrolyzed (SO4(2-)).

    Sulfuric acid is a strong acid.

    Therefore, when a molecule of sulfuric acid is ionized, 2 protons and one sulfate ion are ionized, and NaHSO4 is due to the amount of substances that are neutralized with sulfuric acid when Naoh is neutralized.

    Insufficient, the result is only one proton ionized by each molecule of sulfuric acid, so is there a large amount of H+ and sulfate ions in the solution?

    NaHSO4 is then crystallized to be obtained. When it dissolves, it returns to its pre-crystallization state.

    The acid ions are not hydrolyzed.

    Yes, sodium is a strong base ion, not hydrolyzed, and HSO4- will ionize into H+, SO4

    2-, so only ionization without hydrolysis.

    HSO4* is equivalent to a strong acid in solution, and can completely ionize H*, so it can inhibit hydrolysis and does not hydrolyze itself.

    Water reacts with another compound, which is decomposed into two parts, the hydrolysis part of the hydrogen atom in the water is added to it, and the hydroxyl group is added to the other part, thus giving the reaction process of two or more new compounds. The most industrially used is the hydrolysis of organic matter, mainly to produce alcohols and phenols. The hydrolysis reaction is neutralization or anti-esterification.

    should be the reverse reaction. The hydrolysis of most organic compounds is difficult to carry out smoothly with water alone. Depending on the nature of the hydrolysate, the hydrolysate can be sodium hydroxide aqueous solution, dilute acid or concentrated acid, and sometimes potassium hydroxide, calcium hydroxide, sodium bisulfite, etc.

    This is called alkaline hydrolysis and acid hydrolysis. Hydrolysis can be carried out in batch or continuous mode, with the former usually taking place in a kettle reactor and the latter mostly using a tower reactor. There are four types of typical hydrolysis.

    NaHSO4 is a positive salt, strong acid and alkali salts do not undergo hydrolysis, because the ionized yin and yang ionized hydrolysates cannot destroy the ionization balance of water, so they are neutral. Hydrolysis occurs when strong acids and weak alkali salts, strong alkali and weak alkali salts and weak acid and alkali salts occur.

    The aqueous solution of NaHSO3 is acidic.

    HSO3 - = reversible = H+

    so32-hso3-

    H2O = Reversible = H2SO3 + OH-

    The ionization ability of HSO3- is stronger than that of hydrolysis, so the aqueous solution of NaHSO3 is acidic.

    Acidic NaHSO3===Na+

    HSO3-HSO3-= (reversible) = H++SO3

    2- (Primary).

    HSO3-H2O=(reversible)=H2SO3+OH- (secondary), so it is acidic.

    Sulfurous acid (H2SO3) belongs to the group of electrolytes and is a weak electrolyte. It is also a weak acid.

    Na2SO3 + H2SO4 = Na2SO4 + H2O + SO2 This is a strong acid to a weak acid, indicating that the acidity of sulfuric acid is stronger than that of sulfurous acid.

    If you're comparing dilute sulfuric acid to concentrated sulfuric acid, dilute sulfuric acid is a solution, not an electrolyte.

    H2SO3 is an acid formed by dissolving sulfur dioxide in water and partially combining with water. It is a weak acid. Instability. Can only exist in water. Melt in water is the electrolyte.

    In the molten state, the electrolyte exists as a compound, but in the case of dilute sulfuric acid, which is an electrolyte, it is a mixture.

    Bisulfite ions can be hydrolyzed.

    Sulfurous acid and hydroxide ions: HSO3 are generated

    H2O = H2SO3 + OH- (hydrolysis).

    Bisulfite ions can also be ionized to form sulfite ions and hydrogen ions: HSO3SO3

    h+ (ionization).

    However, the degree of ionization is greater than the degree of hydrolysis, so the NaHSO3 solution is acidic.

    Acidity. acidity

    The universality of aqueous solutions of acids.

    Generally, it can make purple litmus turn red, etc. When the pH value of the solution is below 7, it is acidic. The lower the pH, the more acidic it is.

    Acids can neutralize with alkalis to form salts and water, as well as acid-base indicators that can change color, react with active metals to form hydrogen, and react with salts to form new acids and salts, which are called acidity.

    It may be that the acidity of sulfuric acid and hydrochloric acid is comparable, and it is not divided into strong and weak, but it is only said to reflect volatility.

    The so-called complete ionization refers to the vast majority of ionization, which is not really "complete ionization".

    There are still a small amount of HCL molecules in HCl, but this amount is very small and can be ignored. And sulfate.

    One step is completely ionized, so it is said that sulfuric acid is more acidic than hydrochloric acid.

    In fact, sulfuric acid is not really completely ionized, although the first step of sulfuric acid is 100 ionization, but the second step of ionization is not completely ionized, but in a relatively dilute solution, the degree of ionization is close to 100, so it is generally considered that sulfuric acid is completely ionized.

    The strongest acid, perchloric acid, is the strongest acid because it ionizes more completely than them.
