Hello steemians friend's, my exam of Inorganic Chemistry will come on next Saturday. I have some preparations of exam for the topic "Acid - Base ". Today I want to talk about It.

In this lesson, we discuss about quality of acid - base by these principles.

Arrhenius Theory
Bronsted - Lowry Theory
Lux -Flood Theory
Solvent - System Theory
Lewis A - B Theory

Now we discuss about these Theory :-

1. Arrhenius Theory :- This principle added Arrhenius in 1884. In this theory "when we dissolve any Solvent in water and it gives hydrogen ion that it calls acid and when it gives hydrocsil ion that it calls ".

~~Sorry for my bad handwriting!!!~~

Uses of Arrhenius Theory :-

According to this theory for all of strong acid and strong base are always constant in neutral .
In this theory acid and base are affordable.
In this theory it discribe about catalyst of acid by hydrogen .

Disuses of Arrhenius Theory :-

Some of speaces who not give hydrogen ion are acids.
Gain of hydrogen ion are not include acids.

2. Bronsted - Lowry Theory:- This principle lunched 1923 by Bronsted and Lowry. According to this theory Solvent who gives protons are called acid and Solvent who takes protons are called base.

Uses of Bronsted-Lowry theory:-

From this theory we know about many base's .
This theory say's about sodium carbonet is a base.
According to this theory it fixed feric cloraid is a acid.

Disuses of bronsted lowry theory :-

Many of acid-base reaction aren't have a single .

3. Lux-Flood theory :- It called oxide ion concept and it launched on 1939. In this theory solvent who takes oxide ion are called acid and solvent who give oxide ion are called base.

Uses of Lux-Flood theory:-

Oxide of bases are negitive in there alfa numbers.
Oxide of amphoteric are near about zero(0) in alfa numbers.
Oxide of acid are positive in alfa numbers.

Disuses of Lux-Flood Theory:-

Solvent who haven't Oxide ion are not define by this theory.

4. Solvent-System Theory:- According to this theory acids are these things who Increase positivity of ions and base are dicrease positivity of ion.

Disuses of Solvent-System Theory:-

This theory can't dicribe about physically uses are things.
Many reactions are acid - base, it can't .

5. Lewis A-B theory :- According to the principal things who gain electron are acids and who gives electron are called .

It's my lesson "Acid-Base" in Inorganic chemistry, Unit-5. I'm ready to face exam. Thanks for learn it with me.
