A pKa value is a measurement used for bases and acids. The measurement pH applies to hydronium ion concentrations that are in a solution, whereas pKa only applies to determining the amount of dissociation an acid wants to do in a solution.

The pKa value is a measure of the acidity or basicity of a molecule. It represents the pH at which the molecule is 50% dissociated. pH measures the concentration of hydrogen ions in a solution, while pKa is a specific value for a particular molecule that indicates its tendency to donate or accept protons.
