Understanding, Deriving, and Computing Buffer Capacity

WebFor example, a buffer with [weak acid] = 0.50 M (the [ ] denotes concentration) and [conjugate base] = 0.30 M would have a higher capacity than a buffer with [weak acid] = 0.050 M and [conjugate base] = 0.030 M. Web12 de set. de 2024 · Buffer capacity depends on the amounts of the weak acid and its conjugate base that are in a buffer mixture. For example, 1 L of a solution that is 1.0 M in acetic acid and 1.0 M in sodium acetate has a greater buffer capacity than 1 L of a solution that is 0.10 M in acetic acid and 0.10 M in sodium acetate even though both solutions … stuart kearsey of luton or stevenage
