WebWhat is Ka Chem? The acid dissociation constant (Ka) is used to distinguish strong acids from weak acids. Strong acids have exceptionally high Ka values. 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. WebApr 28, 2024 · This is because a weak base (low Kb value) will generate a strong conjugate acid (high Ka value) (remember that K a K b =Kw for a conjugate acid-base pair). Examples for cations: Cation generated from a strong base: example Na + from NaOH NaOH (aq) → Na+(aq) + HO - (aq) strong base (high Kb) weak conjugate acid (low Ka)
