a solution of a weak acid/weak base and its salt; both components must be present.
has the ability to resist changes in pH |
|
|
identifying buffer systems
|
weak acid and its conjugate base (usually the anion in a soluble salt)
or weak base and its conjugate acid (usually the cation in a soluble salt) |

|
pH of a buffer system
|
just like pH of weak acid except
[conjugate acid/base] is not zero initial[] comes from the salt component |

|
common ion effect
|
the shift in equlibirum caused by the adition of a compound having an ion in common with the dissolved substance
|
|
|
heterogeneous equilibria
|
pertaining to reactions in which the components are in more than one phase
|
|
|
common ion effect
|
the shift in equilibrium caused by the addition of a compound having an ion in common with the dissolved substance

|
|
|
solubility product
|
