WebIn this video, I will teach you how to calculate the new pH of a buffer solution after adding an acid. This skill is useful when asked to calculate the chang... 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.
