WebFeb 10, 2016 · In general the "pKa" is the term used to define the point at which the protonated and unprotonated forms are equal. The pKa is from the negative log of the acid dissociation constant as given by the reaction: H A ↽ − − ⇀ H X + + A X − and the equation: K a = [ H X +] [ A X − ] [ H A] where [ H X +] = [ A X − ] then: K a = [ H X +] X 2 [ H A] and WebFor the titration of a weak acid with a strong base, the pH curve is initially acidic and has a basic equivalence point (pH > 7). The section of curve between the initial point and the equivalence point is known as the buffer region. At the half-equivalence point, the concentrations of the buffer components are equal, resulting in pH = pKₐ.
