pH calculator - How to Find ph from Molarity

WebpH = pKa + log { [salt] / [Acid]} Let [salt] / [Acid] be equal to 10 then, pH = pKa + log 10 pH = pKa + 1 Let [salt] / [Acid] be equal to 1 / 10 then, pH = pKa + log 1 / 10 pH = pKa + log 1 – log 10 pH = pKa – 1 Thus we can quickly determine the pKa value if the pH of the solution is known. pKa from the Titration Curve WebpH = – log [OH –] At pOH 7, the solution is neutral. If the pOH value is less than 7, a solution will be alkaline, while a solution will be acidic if the pOH value is more than 7. We can use numerous parameters to determine the pOH value. pOH from Molarity; pOH from pH; pOH from pKb; pOH from Molarity cafes in spokane wa
