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. WebThe acid dissociation constant is pKa, while the base dissociation constant is pKb. These words are used to make working with extreme values easier. The “p” stands for “negative logarithm in these phrases.” The main distinction between pKa and pKb is that pKa is the negative logarithm of Ka and pKb is the negative logarithm of Kb. sports.com summer camps
