WebWhat is pKa? In simple terms, pKa is a number that shows how weak or strong an acid is. A strong acid will have a pKa of less than zero. More precisely – pKa is the negative log base ten of the Ka value (acid dissociation constant). It measures the strength of an acid — how tightly a proton is held by a Bronsted acid. WebpKa - The pKa value is the negative base -10 logarithm of the acid dissociation constant (Ka) of a solution. The quantitative behavior of acids and bases in solution can be …

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.

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.
