WitrynaTable of Content. Buffer in biological systems. A 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.

The importance of this buffer pair relates to certain key properties: bicarbon-ate is present in a relatively high concentration in the ECF (24mmol/L) and the components of the buffer system are effectively under physiological control: the CO 2 by the lungs, and the bicarbonate by the kidneys. Witryna17 sty 2024 · A buffer solution is an aqueous solution of a weak acid and its conjugate base, or a weak base and its conjugate acid. Its pH changes very little when a small amount of strong acid or base is added to it.
