WebAll other acids in the table are considered weak acids. To compare strength, the ionization of the solution at the same concentration is compared to see which is more strongly acidic/has a lower pH. Hydrofluoric acid, HF (aq), ionizes in water: HF (aq) + H2O (l) ⇋ H3O+ (aq) + F- (aq) The equilibrium law expression would be: WebRule of thumb is: Weak acids have strong conjugate bases, while weak bases have strong conjugate acids. As shown in the above two reactions, if HA is a weak acid, then its conjugate base A ^\text {-} - will be a strong base. Similarly, if A ^\text {-} - is a weak base, then its conjugate acid HA will be a strong acid. How do we define ‘titration’?
