http://saintssnrchem.weebly.com/ka-and-pka.html Web15 okt. 2024 · What is the relation between pH and PKA or pKb values? The equation for the pH of a solution is pH = -log [H+]. The pKa value is of an acid is pKa = -log (Ka). There is a similar relationship for pKb, where pKb = -log (Kb). Here Ka and Kb are the equilibrium constants for your acid/base. Which is the correct value of the Ka constant?
Web8 dec. 2024 · In terms of calculation, pH is the -log of the concentration of H + ions. You can also calculate pH if you are given pOH, with the equation pH+pOH=14. If you are given concentration of OH - ions, you can find pOH and solve for pH as well. pH and pK A are not directly related through calculations. Web27 aug. 2024 · 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.
