Explore Kinetic Citation/Attribution WebAlthough the ionization constants for all weak acids are relatively small (otherwise the acid would not be a weak acid), they do vary in magnitude. The smaller the constant, the less the acid ionizes, and the weaker the acid. Table 15.5 lists the acid ionization constants for a num-ber of common weak acids in order of decreasing acid strength.

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
