WebSep 1, 2024 · Because the phosphate salts had better buffering capacity at pH 6.8 than the citrate salts under our conditions (i.e., at the same IS, phosphate salts were more concentrated on a molar basis), the pH at denaturation temperature was closer to 6.8 for phosphates at sufficient concentration. WebThe buffer is a mixture of a weak acid and its conjugate base. The buffering capacity of a solution is determined using the Henderson-Hasselbalch Equation, and the closer the ratio of acid to conjugate base is to one the higher buffering capacity. A buffer also can consist of a weak base and its conjugate acid as well. pH = pKa + log ([A-] / [HA]) philips beauty
