Definition Ka, acid dissociation constant, is a ratio that indicates the extent of dissociation of acid under a specific temperature, i.e. how strong the acid is. Consider this reaction: AH2(aq) → A-(aq) + 2H+(aq) This equation denotes the ionization of an acid in water. For example, 10 M of A- and 10M of H+ presents in the solution, while only 1 M of AH remains. After AH is dissolves in water, the Ka of AH is : [100]^2 * [100] …
