How to determine greatest buffering capacity

WebJan 16, 2024 · For calculation of pH for a buffer solution we should use equation pH = pKa + log [b]/ [a]. When [b]/ [a] is 10, then one unit will be added to pKa in the above equation. In addition, when [b]/... 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.
