WebFeb 24, 2024 · What Is the pH Formula? The pH equation is most often written in the form pH = -log_ {10} [H^ {+}] pH =−log10[H +] Here, the quantity in brackets is the molarity of H+ ions in the solution. Thus, if you know the molarity, you can get the pH value and conversely. Examples of pH Calculations 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 order connecticut tax forms https://dogwortz.org
