Worked example: Finding the percent ionization of a weak acid

Webp K a = − log K a. Acid dissociation constant is the equilibrium constant of the dissociation of ions of an acid in an aqueous solution. Consider a weak acid H A. Weak acids do not dissociate completely in aqueous solution. The equilibrium for the dissociation of such acids can be expressed as. H A + H X 2 O ↽ − − ⇀ H X 3 O X + + A X −. WebStrong acids and strong bases refer to species that completely dissociate to form ions in solution. By contrast, weak acids and bases ionize only partially, and the ionization reaction is reversible. Thus, weak acid and base solutions contain multiple charged and uncharged species in dynamic equilibrium.

In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted $${\displaystyle K_{a}}$$) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid–base reactions. … Meer weergeven The acid dissociation constant for an acid is a direct consequence of the underlying thermodynamics of the dissociation reaction; the pKa value is directly proportional to the standard Gibbs free energy change … Meer weergeven An acid is classified as "strong" when the concentration of its undissociated species is too low to be measured.
