WHAT DO ALL ACIDS AND ALL BASES HAVE IN COMMON?

Ions : charged atoms are known as ions.

Ions are two types: 

(I)   Cation: It carries (+) Positive charge on atom.

(II)   Anion: It carries (-) Negative charge on atom.

all acids generate hydrogen gas on reacting with metals, so hydrogen seems to be common to all acids. but all compounds having hydrogen are not acids. As acids have H⁺ Ion. For example we take three substances,

Vinegar, glucose and alcohal 

The chemical formula are;

Vinegar  → CH₃COOH,

Glucose → C₆H₁₂O_6, 

_Alcohal → _​ CH₂CH₃OH, 

​These all have hydrogen.
