WitrynaA buffer is an aqueous solution made up of a weak acid and its salt (acid buffer) or a weak base and its salt (base buffer) (basic buffer). When a tiny amount of strong acid or base is given to it, its pH varies very little, and it is thus used to keep a solution’s pH stable. Buffer solutions are utilised in a variety of chemical processes. Witryna30 sty 2024 · The effective buffer range is of magnitude 2 pH units with the pKa as the midpoint. pKa = − log10Ka = − log10(1.75 × 10 − 5) = 4.756 Hence, the buffer range would be 3.75 to 5.75.
