A buffer … Webb29 aug. 2024 · A buffer is a solution (or a substance) that has the ability to maintain pH and bring it back to its optimal value. It does this by the additional or removal of hydrogen ions. Buffers working in the body fluid adjust the pH level of the blood and function to lower pH if its level rises above 7.4 by making the blood slightly more acidic 1 3.
