WebJan 17, 2024 · The pH of our buffer is equal to 6.4. What buffers are there in human blood? There are four primary buffers that help maintain the pH of human blood: Bicarbonate … WebTherefore, the pH of the buffer solution is equal to the pKa value of the weak acid minus one. This value for the pH represents the lower limit of the effective pH range. By the calculations that we've just done, we've seen that the effective pH range of a buffer is plus or minus one of the pKa value of the weak acid.
