    The strong alkali weak salt does not react with the alkali, because it is also alkaline, the strong acid and weak alkali salt are acidic, and it has the general nature of acid, and the strong alkali weak salt and the strong acid and weak alkali salt are strong and the nature of the salt.

    Sodium bisulfate and barium hydroxide:

    2NaHSO4 + BA(OH)2=BASO4 +2H2O+Na2SO4 You can use the ion equation: for example, in this reaction, sodium bisulfate ionizes Na+ and H+ and sulfate ions in water.

    Barium hydroxide ionizes OH- and BA2+ ions. Ba2+ binds to Na+ and sulfate ions, and OH- and H+ bind.

    It's written out.

    Another example is NaHCO3, which ionizes Na+ and HCO3- ions and Ba2+ and sulfate ions.

    2NaHCO3 + BA(OH)2=BAC3 +Na2CO3 + 2H2O In short, you see whether they belong to strong electrolytes or weak electrolytes.

    Strong acid and weak alkali salt or something, you look at their hydrolysis equation, for example: sodium carbonate is a strong alkali and weak salt, hydrolysis is divided into sodium hydroxide and carbonic acid, as for the sodium bisulfate and barium hydroxide you said, they are acid-base neutralization equations should be written

    Not necessarily, but the one you're talking about will react and produce water and precipitation.

    The reaction between salts and salts can occur when the conditions are met.

    The concept of the reaction of Lizhen Bimuzi: The reaction in which ions participate or are generated in the reaction is called ion reaction. In the middle school stage, reactions that are limited to reactions carried out in solution can be said to be ionic reactions, which are a type of reaction in which electrolytes are involved in aqueous solutions.

    Characteristics of ionic reaction: the reaction rate of ionic reaction is fast, and the reaction between the corresponding ions is not disturbed by other ions.

    Types of ionic reactions: metathesis reaction, Huiqing salt hydrolysis reaction, redox reaction, complexation reaction.

    Ion reaction conditions: After ion exchange, one of the three types of precipitation, gas, and weak electrolyte must be generated before the reaction can occur; The dihydrolysis reaction requires the formation of more difficult-to-dissolve substances or weak electrolytes in order for ionic reactions to occur; Ion reactions can only be carried out by generating complex ions that are more stable than simple ions; In the electrolyte solution, the ionic reaction can be carried out only when the reaction can satisfy the redox reaction law of "forced weakness".

    is the "homoionic effect" and does not affect the ksp

    That is, adding a strong electrolyte with the same ions as the electrolyte to the weak electrolyte solution can reduce the ionization degree of the weak electrolyte, which is called the homoionic effect.

    For example, BaSO4(S)=BA2+(AQ)+SO42-(AQ)KSP= = [BA2+] SO42-], if the same ion SO42- is added to the saturated solution, the ion concentration increases, and the equilibrium moves in the direction of forming precipitate, that is, reducing the solubility of barium sulfate.

    In layman's terms.

    Suppose it is possible to dissolve g BaSO4 in pure water, but if it is dissolved in a solution containing SO42-, the amount of dissolution will be reduced.

    Hope it helps.
