pH, pKa, and the Henderson-Hasselbalch Equation

Jan 30, 2020·The pH is a measure of the concentration of hydrogen ions in an aqueous solution. pKa (acid dissociation constant) and pH are related, but pKa is more specific in that it helps you predict what a molecule will do at a specific pH.Essentially, pKa tells you what the pH needs to be in order for a chemical species to donate or accept a proton.
