WebMar 6, 2024 · By contrast, the acetate buffer’s pH after adding the same amount of HCl is 4.74. Thus, the pure water solution sees its pH fall from 7 to 2 (5 pH units), whereas the buffered solution saw its pH drop from 4.76 to 4.74 (0.02 pH units). Clearly, the buffer minimizes the impact of the added protons compared to the pure water. Buffer capacity WebBuffers Because it is absolutely essential that blood pH be maintained within the narrow range, the body has several mechanisms to regulate the H + concentration of the blood. One important defense employed by the body is the various buffer systems. Buffers are chemicals that tend to resist changes in pH.
