Ionic Dissociation. Ionic dissociation is a process where a salt, when dissolved in water, breaks up (dissociates) into two or more charged ions. Consider a salt (AB) made up of an acid (A) and a base (B). Now the salt will dissociate into acid ions (negatively charged) and base ions (positively charged) and some of the salt will remain undissociated (uncharged). The ionic dissociation can be described by the following equation, . Applying the law of mass action in its simplest form, in which concentrations (c) are employed instead of activities,   where (k) is known as the dissociation constant.
