![]() In addition, the smaller the pKa value, the stronger the acid. ![]() However, it is often forgotten, that when defined as above, pKa depends on buffer concentration and temperature. ![]() The pKa of a buffer is commonly perceived as the pH of the said buffer when the concentrations of the two buffering species are equal, and where the maximum buffering capacity is achieved. PH is equal to the sum of the pKa value and the log of the conjugate base concentration divided by the weak acid concentration. The acid and base dissociation constants are usually expressed in terms of moles per liter (mol/L). Similarly, Kb is the base dissociation constant, while pKb is the -log of the constant. Its value is directly related to the structure of the given compound. PKa is an acid dissociation constant used to describe the acidity of a particular molecule. 24 How do you find pKa from pH and volume? What is a pKa in chemistry?
