Acid salt is h in it? Yes. Such as: CaHCO?

Basic salt means it contains OH? Yes. Such as: AlOHCO?

Normal salt: in the salt produced by the complete neutralization of acid and alkali, there will be no hydrogen ions in acid and no hydroxyl ions in alkali, only metal cations and acid ions, which are neutral salts;

Acid salt: the cation generated during ionization contains hydrogen ions in addition to metal ions (or ammonium ions), and the anion is a salt of acid ions. Because anions contain hydrogen atoms that can be ionized in water, they are called "acid" salts;

Basic salt: the anion generated during ionization includes hydroxide ion in addition to acid ion, and the cation is metal ion (or ammonium cation).

Extended data:

Normal salt: strong acid and alkali salt, strong acid and weak base salt, strong acid and weak base salt, weak acid and weak base salt;

Acid salt: the acid salt of strong acid (such as sulfuric acid) and a small amount of medium-strong acid (such as phosphoric acid) is acidic;

Basic salt: Basic copper carbonate and basic magnesium chloride are all basic salts.

It should be noted that when the acid salt exists in the form of ionic crystal, the anion does not ionize hydrogen ions (but sodium bisulfate (NaHSO? ) is an exception, which can ionize H? Hydrogen ion is a part of acid radical ion. In the molten state, acid radical ions are not ionized. (Sodium bisulfate does not ionize in molten state)

When acid reacts with alkali, the hydroxyl ions in weak alkali are partially neutralized, and the generated salt is basic salt. Monobasic alkali can't form basic salt, but binary alkali or polybasic alkali can form basic salt. The composition and properties of basic salts are complex and diverse. Basic copper carbonate Cu? (OH)? CO? And basic magnesium chloride Mg(OH)Cl hydroxyapatite Ca? (OH)(PO? )? All belong to basic salts.
