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.

8.3: pKa Values - Chemistry LibreTexts

WebIn 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.

Web18 de abr. de 2024 · The conjugate acid of ammonia, NH 4 (+), is 9.2 . Equivalently, we can say that the pK a H of ammonia is 9.2. This puts it in-between pyridine and piperidine on the basicity scale. Note that it’s very important not to confuse pKaH with pKa. The pK a H of ammonia is 9.2, which measures the acidity of its conjugate acid, NH 4 (+).
