WebStrong acids have extremely high Ka values. The equilibrium constant for acid dissociation determines the Ka value. The more the acid dissociates, the higher the Ka. What is KF and KR. In terms of concentration, the kf/kr=equilibrium constant is represented by Kc. The following reaction’s equilibrium constant is written as follows: aA bB cC dD. WebSep 7, 2024 · The Ka value is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates. Thus, strong acids must dissociate more in water. In contrast, a weak acid is less likely to ionize and release a hydrogen ion, thus resulting in a less acidic solution. How do you find Ka in a titration?

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 understood only if their pKa values are known.
