WebFeb 13, 2024 · pKa = -log Ka where each bracketed term represents the concentration of that substance in solution. The stronger an acid, the greater the ionization, the lower the pKa, and the lower the pH the compound will produce in solution. WebAug 29, 2014 · Using the properties of logarithms, Equation 2.2.8 can be rewritten as. 10 − pKw = 10 − 14. The equation also shows that each increasing unit on the scale decreases by the factor of ten on the concentration of H +. Combining Equations 2.2.4 - 2.2.6 and 2.2.8 results in this important relationship: pKw = pH + pOH = 14.

"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. Ka values can provide the same ... " - Pka alta

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.
