Definitions:
Buffer - a solution that resists a change in pH (Ex: Blood)
Amphoteric - a substance that can act as both an acid and base (Ex: H2O, H2SO4)
Conjugate Acid - the species formed when a base gains one hydrogen ion
Conjugate Base - the species formed when an acid loses one hydrogen ion
-protic - a substance that loses a certain amount of hydrogen ions
Equilibrium:
* In buffers, if a small amount of acid is added, the hydrogen ion concentration increases, thus changing the equilibrium to the left * If a small amount of base is added, the hydroxide ion concentration increases, thus changing the equilibrium to the right * Equilibrium lies to the right in a strong acid and left in a strong base (As pH increases, equilibrium shifts to the right)
More:
* Weak acids/bases do not conduct electricity as well as strong acids/bases * Acids/bases react with one another to form a salt and water (neutralization reaction) *
