WebJan 17, 2024 · pKa of a carbonate buffer equals 6.4. Let's assume that both the acid's and conjugated base's concentrations are equal to 6 M. Utilize the equation: pH = pKa + log ( [A⁻]/ [HA]) pH = 6.4 + log (6 M/6 M) pH = 6.4 + log (1) pH = 6.4 + 0 pH = 6.4 The pH of our buffer is equal to 6.4. What buffers are there in human blood? WebSo, now that we're adding the conjugate base to make sure we have roughly equal amounts, our pH is no longer 2. It might be somewhere like a 5. So now we have a strong buffer with a lot of capacity, but our pH of this buffer solution is very different from the pH of just the weak acid/conjugate base we started with.
