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. picasso three women https://amdkprestige.com

The " pKa " of a base is just the pKa of the conjugate acid of that base. it has the equilibrium constant: Kb = (HBX +)(OHX −) (B). the equilibrium constant is: … WebpKa = -log 10 Ka. The acid is more potent if its pKa value is lower. Acetic acid, for example, has a pKa of 4.8, and lactic acid has a pKa of 3.8. Lactic acid is a more vital acid than acetic acid, as evidenced by its pKa values. Because it uses small decimal quantities to explain acid dissociation, pKa is used.
