What is positive salt and what is the definition of positive salt?

Salts in chemistry are divided into normal salts, acid salts, basic salts, and double salts. In the salt generated by the complete neutralization of acid and alkali, there will be no hydrogen ions in the acid, and there will be no hydroxide ions in the base, only metal cations and acid ions, and the neutral salt is the normal salt.

For example, NaHCO3 is an acid salt, and Na2CO3 is a normal salt.

As opposed to acid salts, for example, NaCO3 is a positive salt, while sodium bicarbonate is an acid salt! Another example is Na2S normal salt, potassium sulfate positive salt, adding hydrogen is an acid salt!

Salts that contain only these two ions are normal salts.

Such as: Na2CO3, KCI, etc.

Those with hydrogen ions are acid salts. Such as: NAHCo3

The one with hydroxide ions is a basic salt. Such as Cu2(OH)2CO3, etc.

There is also a special salt: NH4NO3 ammonium nitrate is also a normal salt.

It refers to the salt formed by the complete neutralization of acid and alkali, which does not contain hydrogen ions in acids, nor hydroxide ions in alkalis, but only metal cations and acid ions.

Salts that contain neither ionized hydrogen ions nor hydroxide ions.

A combination of metal cations and acid aniones.

The normal salt is as follows:Positive salt is the salt formed by the complete neutralization of acid and alkali, there will be no hydrogen ions in the acid, there will be no hydroxide ions in the base, only metal cations.

and salts of acid ions. Positive salts are the products of complete neutralization of acids and bases, but the aqueous solution of normal salts is not necessarily neutral, such as Na2CO3 (sodium carbonate.

The solution is alkaline, and the (NH4)2SO4 (ammonium sulfate) solution is acidic.

Classification of normal salts:Normal salts are roughly divided into four types: strong acid and strong alkali salts, strong acid and weak alkali salts, strong alkali and weak alkali salts, and weak acid and weak alkali salts.

The main reactions generated are:

hcl+naoh=nacl+h2o

H2SO4+CU(OH)2 = CUSO4+2H2OH2SO4+2NAOH=NA2SO4+2H2O, the above content refers to Encyclopedia - Positive Salt.

Definition: A salt that contains neither ionized hydrogen ions nor hydroxide ions.

Normal salt is the product of complete neutralization of acid and base, but the aqueous solution of normal salt is not necessarily neutral, such as Na2CO3 (sodium carbonate) solution is alkaline, (NH4) 2SO4 (ammonium sulfate) solution is acidic. In the salt formed by the complete neutralization of acid and alkali, there will be no hydrogen ions in the acid, and there will be no hydroxide ions in the base, only metal cations and acid ions, and such salts are positive salts. Reaction to generate positive salts.

Expansion: Basic salts: When an acid reacts with a base, the hydroxide ions in the weak base are partially neutralized, and the salt produced is an alkaline salt.

Monobases cannot form basic salts, and only dibasic bases or polybases can form basic salts. The composition and properties of basic salts are complex and diverse. Basic copper carbonate Cu2(OH)2CO3 and basic magnesium chloride MG(OH)Cl are all basic salts.

Positive Destruction Salt: A salt that contains neither ionized hydrogen ions nor hydroxide ions. Positive salt is the product of complete neutralization of acid and base, there will be no hydrogen ions in acid, there will be no hydroxide ions in alkalis, only metal cations and acid ions, which are neutral salts.

1. Strong acid and alkali salt

Hydrolysis does not occur because the anions and cations ionized by their ionization cannot destroy the ionization balance of water, so they are neutral.

2. Strong acid and weak alkali salt

We call the weak alkali part weak yang, the weak alkali ions can hold the ionization of hydroxide ions from the water, destroy the ionization balance of water, and make the ionization of water move forward, as a result, the concentration of hydrogen ions in the solution is greater than the concentration of hydroxide Xiaofan ions, making the aqueous solution acidic.

3. Strong alkali and weak salt

In the same way, the weak yin holds the hydrogen ions ionized from the water, so that the concentration of hydroxide ions in the solution is greater than the concentration of hydrogen ions, making the solution alkaline.

4. Weak acid and weak alkali salt

The weak acid part holds the hydrogen, and the weak alkali part controls the hydroxide group to generate two weak electrolytes, and then compare their ionization constants Ka and Kb values.
