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. WebIt is customary to use the common pKa scale for both acids & bases: Lower the pKa of HA, stronger the acid in terms of its ability to release protons. Higher the pKa of BH+, the conjugate acid of base, B, stronger the base B in terms of its ability to accept protons.ssing the strength of Weak Acids & Bases by a common pKa scale

WebTitration curves reveal the pKa of weak acids. 2.3 Buffering against pH Changes in Biological Systems Buffers are mixtures of weak acids and their conjugate bases. The Henderson-Hasselbalch equation relates pH, pKa, and buffer concentration. Weak acids or bases buffer cells and tissues against pH changes.

WebThe pKa value is one way for determining an acid's strength. The negative log of the acid dissociation constant, or Ka value, is pKa. A lower pKa value denotes a more potent acid.
