Web10 jul. 2024 · This turns out to be the case when the concentrations of the conjugate acid and conjugate base are approximately equal (within about a factor of 10). For example, we know the K a for hydroflouric acid is 6.6 x 10 -4 so its pK a = -log (6.6 x 10 -4) = 3.18. So, a hydrofluoric acid buffer would work best in a buffer range of around pH = 3.18. WebWe can construct an acid dissociation expression for strong acids and calculate their Ka and pKa values. These values indicate that the products of a strong acid reaction are heavily …
