WebApr 19, 2024 · Factors that affect buffer capacity: The relative concentrations of the weak acid and its conjugate. ... What makes a buffer and how does it work? A buffer is made by mixing a large volume of a weak acid or weak base together with its conjugate. A weak acid and its conjugate base can remain in solution without neutralizing each other. The same ... WebThe pH of a buffer is determined by two factors; 1) The equilibrium constant Ka of the weak acid and 2) the ratio of weak base [A-] to weak acid [HA] in solution.. 1) Different weak acids have different equilibrium constants (K a).K a tells us what proportion of HA will be dissociated into H + and A-in solution. The more H + ions that are created, the more …
