Ionization constants of weak acids

WebThe ionization constant expression for the above acid dissociation, using H+ in place of H 3 O+for simplicity, is as follows: Equation 1: K a= [H+][A ] [HA] Other useful definitions for solving acid-base problems include: K w+= [H 3 O ][OH−] = 1.00×10−14K w = K a ×K b pH = −log[H+] − pOH = −log[OH ] pH + pOH = 14 pK a = −log K 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 …
