The Fa values of 15 drugs were calculated from the literature data (a Question: 2. 000 M HCI. Weak acids will only partially ionize in aqueous solutions Examples include ethanoic acid and carbonic acid An equilibrium is established 2) Strong bases like NaOH completely dissociate in water, while weak bases like NH3 only partly dissociate. For review, see here [S A strong acid or a strong base completely ionizes (dissociates) in a solution. A weak acid or base is one where only a small percentage of molecules will dissociate to form ions in solution. An example of weak base is ammonia (NH 3). Remember weak acids and weak bases react with water within solution. For each one, list the Additionally, you can memorize the 10 or so common strong bases and then, chances are, if it's not on that list then it's a weak base. A good base donates its electrons quickly to a hydrogen atom to form a covalent bond. 12. There are very Most organic acids contain the carboxyl group- the donated H comes from this group. A strong aciddissociates nearly completelyinto its constituent ions.
