Acids undergo ionization in aqueous solution. The degree of ionization of an acid in an aqueous solution is called th e strength of that acid. Degree of ionization is denoted by the letter alpha (α).
α=NumberofionisedacidmoleculesTotalnumberofacidmolecules×100
On the basis of the degree if ionization, the acids are classified as
On the basis of the degree of ionization, the acids are classified as
(a) strong acids (high degree of dissociation)
(b) weak acids (low degree of dissociation)
