Salt can be divided into single salt and double salt. Single salt has normal salt, acid salt and alkaline salt, and double salt has double salt and double salt. Among them, acid salts contain hydrogen ions in addition to metal ions and acid ions, and basic salts also contain hydroxide ions in addition to metal ions and acid ions. The compound salt can be dissolved in water, and can generate the same combined salt as the original salt ion. When the double salt is dissolved in water, a double salt complex with complex ions different from the original salt can be formed.

Strong base weak acid salt is a salt produced by the reaction of strong base and weak acid, which is alkaline when dissolved in water, such as sodium carbonate. Strong acid and weak base salt is a salt produced by the reaction of strong acid and weak base, which is acidic when dissolved in water, such as ferric chloride.

Salts containing hydroxyl ions are called basic salts, such as basic copper carbonate [Cu2(OH)2CO3].

Salts that do not contain hydroxyl ions and hydrogen ions are called normal salts, such as sodium chloride (NaCl); Sodium carbonate (Na2CO3). There are also double salts (such as alum).
