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.

WebFor methyl red, the pKa value is approximately five. And the goal is to match the pKa value as closely as possible to the pH at the equivalence point. But since the pH at the equivalence point is between eight and 10, that's too far away from five. So by looking at the pKa value, we know that methyl red is not a good fit for this titration. springdale used carsWebNov 11, 2024 · pK a is the negative base-10 logarithm of the acid dissociation constant (K a) of a solution. pKa = -log 10 K a The lower the pKa value, the stronger the acid.
