Term
Weak Acid/ Strong Base pH Titration:
At the Initial Point |
|
Definition
HA --> H+ + A-
Ka= x^2 / [HA] - x |
|
|
Term
Weak Acid/ Strong Base pH Titration:
In the Buffer Region |
|
Definition
HA + OH- --> A- + H2O
Calculate [HA] remaining and [A-] formed then apply H-H equation |
|
|
Term
Weak Acid/ Strong Base pH Titration:
At the equivalence Point |
|
Definition
Assume all HA has been converted to A-
A- + H2O --> HA + OH-
Kb = x^2 / [A-] - x
[H+] = Kw / x |
|
|
Term
Weak Acid/ Strong Base pH Titration:
Beyond the Equivalence Point |
|
Definition
| Assume the acid and base were consumed completely at the equivalence point. Then start over and calculate [OH-] directly from (mol base added after the equivalence point) / tot vol |
