AP Chemistry Acid/Base Equilibrium Quiz Name Class
Introduction. Originally the terms acid and base referred to taste. The practice of classifying substances according to their acidic (sour) or basic (alkaline or bitter) properties dates back to ancient times....

a) HF(aq) + H2O(l) F-‐(aq) + H3O+(aq) (note 2-way arrow) Acid 1 Base 2 Base 1 Acid 2 The reactants are favoured in this equilibrium because the HF is a weaker acid than H3O+ (and H2O is a weaker base than F-‐) and acid-‐base equilibria always favour the weaker species.
- •In every acid-base reaction, the position of the equilibrium favors the transfer of a proton from the stronger acid to the stronger base. •H + is the strongest acid that can exist in equilibrium …
- At the half-equivalence point (where the volume of the base added is exactly half its volume at the equivalence point), the concentration [HX] of the weak acid equals the concentration [X¯] of its anion.
