An example of a weak acid is acetic acid (ethanoic acid), and an example of a weak base is ammonia. Because these molecules do not fully dissociate, the pH shifts less when near the equivalence point. The equivalence point will occur at a pH within the pH range of the stronger solution, i.e. for a strong acid and a weak base, the pH will be <7.

Water We typically talk about acid-base reactions in aqueous-phase environments -- that is, in the presence of water. The most fundamental acid-base reaction is the dissociation of water:. In this reaction, water breaks apart to form a hydrogen ion (H +) and a hydroxyl ion (OH-).In pure water, we can define a special equilibrium constant (K w) as follows:
Acid/Base Neutralization •A salt is any compound that can be derived from the neutralization of an acid and a base. •The word "neutralization" is used because the acid and base properties of H+ and OH- are destroyed or neutralized. •In the reaction, H+ and OH- combine to form HOH or H 2 O (water molecules).
