WebFeb 9, 2024 · Consider this graph of the titration of a weak acid and a strong base: The buffering region is strongest at the midpoint of titration because there is equal concentrations of acetic acid and its conjugate base. My question is why at the midpoint of titration does the concentration of the acid equal the concentration of its conjugate base? WebNote that the generic formula HA is used for each acid and A- for the conjugate base in both cases. -Strong acid: [H3O+], A- -Weak acid: HA Calculate the pH and [OH-] of a solution of a 1.5 M solution of HCl. pH = -0.18 [OH-] = 6.7*10^-15 Acid dissociation is represented by the general equation HA + H2O (l) ⇌ H3O+ (aq) + A- (aq).
