Title: what is the difference between degree of dissociation and degree of acidity?
Post by: Shah on February 22, 2011, 02:13:34 PM

Is degree of dissociation different from degree of ionization?

dissociation and ionization are two different processes. Of course that means that the degree of dissociation is different than the degree of ionization.

With regard to the subject of your post, strong acids (HCl, H2SO4, HNO3, HClO4, etc) essentially dissociate completely in water:

HCl + H2O  -->  H3O+  +  Cl-   

Weak acids only dissociate sparingly in aqueous medium.
