What is common to all acids, bases and salts?

Acids:

(1) All acids produce hydrogen ions, H+, in aqueous solution.
(2) Acids have sour taste.
(3) Acids dissolve in water to form solutions which conduct electricity.
(4) All acids turn damp blue litmus paper red.
(5) Acids react with reactive metals to form hydrogen and a salt.
(6) Acids react with carbonates to form a salt, CO2 and H20.
(7) Acids react with metal oxides and hydroxides to form a salt and H20.

Base:

(1) Base is any metal oxide or hydroxide.
(2) Base contains either oxide ions O2- or hydroxide ions, OH-.
(3) Base reacts with an acid to give a salt and H20.

Note: Bases include Alkalis, which produce OH- when dissolved in water, but not all bases are hydroxides. They can be metal oxides O2- without the H too.

Salts:

(1) All salts are ionic compounds.
(2) A salt contains a positive metal ion and a negative non-metal ion.
(3) Salts are formed when a metallic ion replaces one or more hydrogen ions of an acid.

The acids contain more H+ ions, increase in H+ ions increase.

The acidic property that's why hydrogen is common in all acids.

All acid essentially should have a tendency to produce a proton.

H+ is a ready proton which almost all acid produce.

H+ is the lightest chemical in the universe. So, h+ can be used in acids and mostly h+ is in the nucleus.

According to the Arrhenius concept, acid gives H+ or proton so this the property of acid.

h+ shows the property of acid they have capacity to loss electron.

But it's not applicable for Lewis acids (Al2O3, BF3...etc)

I don't understand this bases and acids. Help me please.

Acids is produce h+ ions and bases produce oh- ions.

Most of the acids start with h+ and bases with oh-.
