While the bases are those compounds that furnish the hydroxyl ions, OH– in the aqueous medium. The degree of ionization of the acids and bases helps determine its strength. On the basis of different acidic and basic compounds, the degree of ionization may differ
The degree of Ionisation refers to the strength of an acid or a base. A strong acid is said to completely ionize in water whereas a weak acid is said to only ionise partially. As there are different degrees of ionization of acids, there are also different levels of weakness for which there is a simple quantitative way to express.
Since the ionization of a weak acid is an equilibrium, the chemical equation and an equilibrium constant expression can be stated as :
HA ( aq ) + H2O ( l ) H3O+ ( aq ) + A–
Ka = [ H3O+ ] [A–] / [HA]
Equilibrium Constant for ionisation of an acid defines its Acid Ionisation Constant (Ka). However, the stronger the acid, the larger will be the acid ionisation constant (Ka). This means that a strong acid is a better proton donor. As a result of the concentration of the product in the numerator of the Ka, the stronger the acid the larger is the acid ionisation constant (Ka).

Ionisation of bases releases (OH-) ions.
