WebFor a weak acid or base, the equilibrium constant for the ionization reaction quantifies the relative amounts of each species. In this article, we will discuss the relationship between the equilibrium constants K_\text {a} K a and K_\text {b} K b for a conjugate acid-base pair. An aqueous solution of hydrofluoric acid, a weak acid, contains ... WebThe ionization-constant expression for a solution of a weak acid can be written as: K a = [ H 3 O +] [ A −] [HA] Rearranging to solve for [H 3 O +] yields: [ H 3 O +] = K a × [HA] [ A −] Taking the negative logarithm of both sides of this equation gives −log [ H 3 O +] = −log K a − log [ HA] [ A −], which can be written as Web23.2 Acid and Base Ionization Constants. The relative strength of an acid or base is the extent to which it ionizes when dissolved in water. If the ionization reaction is essentially complete, the acid or base is termed strong; if relatively little ionization occurs, the acid or base is weak.As will be evident throughout the remainder of this chapter, there are many … greek translation old testament
