<Li> Ammoniumhydroxide, NH OH </Li> <Ul> <Li> An example of a weak base is ammonia . It does not contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions . </Li> <Li> The position of equilibrium varies from base to base when a weak base reacts with water . The further to the left it is, the weaker the base . </Li> <Li> When there is a hydrogen ion gradient between two sides of the biological membrane, the concentration of some weak bases are focused on only one side of the membrane . Weak bases tend to build up in acidic fluids . Acid gastric contains a higher concentration of weak base than plasma . Acid urine, compared to alkaline urine, excretes weak bases at a faster rate . </Li> </Ul> <Li> An example of a weak base is ammonia .
