WebSo the $\ce {HF}$ in $\ce {H2O}$ isn't buffer because there isn't almost any $\ce {F-}$ to be considered as conjugated acid. So if you add some acid there will not be enough $\ce {F …
WebA buffer will only be able to soak up so much before being overwhelmed. This is known as its capacity. It's the reason why, in order to get the best buffer possible, you want to have roughly equal amounts of the weak acid [HA] and it's conjugate base [A-].
