WebDefinition: The acid dissociation constant (Ka) is a quantitative measure of an acid’s strength in solution. It is typically expressed as a ratio of the equilibrium concentrations (in mol/L): Ka = [A –][H +]/[HA] . The pKa, which is equal to -log 10 (ka), is frequently used to express the Ka values. The greater the value of pKa, the greater the degree of dissociation. WebAug 1, 2016 · Strong acids typically possess large Ka values.

WebFeb 4, 2024 · A large Ka value indicates a strong acid because it means the acid is largely dissociated into its ions. A large Ka value also means the formation of products in the reaction is favored. A small Ka value means … WebThe strongest acid is perchloric acid on the left, and the weakest is hypochlorous acid on the far right. Notice that the only difference between these acids is the number of oxygens bonded to chlorine. As the number of oxygens increases, so does the acid strength; again, this has to do with electronegativity.
