WebSep 11, 2024 · We can use a multiprotic weak acid to prepare buffers at as many different pH’s as there are acidic protons, with the Henderson–Hasselbalch equation applying in each case. For example, for malonic acid (p Ka1 = 2.85 and p Ka2 = 5.70) we can prepare buffers with pH values of pH = 2.85 + logCHM − CH2M pH = 5.70 + logCM2 − CHM −

WebHowever it's unnecessary to calculate the pH of strong acid solution using the Henderson-Hasselbalch equation since we can do so using stoichiometry of H+ and assume that strong acids dissociate ~100%. So it's possible to use the Henderson-Hasselbalch equation, but it creates unneeded work when simpler methods are possible. Hope that helps. WebpH of acid buffer = pKa + ( [salt]/ [acid]) The equation is the Henderson-Hasselbalch equation, popularly known as the Henderson equation. Preparation of Base Buffer Consider base buffer solution, containing a weak base (B) and its salt (BA) with strong acid. pOH, can be derived as above, pOH of a basic buffer = pKb + log ( [salt]/ [acid])
WebA pH buffer is a solution that resists changes in pH when acids or bases are added to it—typically, a solution of a weak acid and its conjugate base.
