WebSo let's go ahead and look at all the possible scenarios for these three things. We're going to start with the simplest possible scenario, which is that pH is equal to pK_a. When pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one. Webdenominator by [HA] yields the imperfect -buffer base capacity formula β. b = 9[A. −][HA] 10[A. −]+[HA]. In continuation, consider eq 2. Here a strong base is being added to the buffer solution.
